The Sleep Vault

What Is the Circadian Rhythm?

Think of it as your baby's internal 24-hour clock that tells them when to wake, when to sleep, and when to feel alert or tired. It runs in the background, controlling hormones, body temperature, and digestion.

How It Works

• Morning: The brain regulates chemicals that promote alertness and wakefulness (cortisol rises).
• Afternoon: A natural energy dip — you might notice your baby is ready for a nap.
• Evening: As darkness falls, the brain releases melatonin, helping prepare the body for sleep.
• Night: The body repairs and restores itself during sleep.

In Infants

At birth, babies don't have a developed circadian rhythm — their sleep is polyphasic, meaning lots of short periods of sleep throughout day and night. From around 2 months, their internal clock starts to develop, and by 3–6 months many babies begin sleeping in longer stretches at night.

What Supports a Good Circadian Rhythm?

• Bright natural light during the day (especially morning)
• Darkness at bedtime and through the night
• Consistent sleep and wake times
• A predictable bedtime routine

Melatonin — The Sleep Hormone

Released by the pineal gland in the brain in response to darkness. As darkness sets in, melatonin levels rise, promoting drowsiness and helping the body prepare for sleep. Even low levels of artificial light at night can suppress melatonin production — which is why a dark sleep environment matters so much.

Cortisol — The Stress Hormone

Cortisol follows the opposite rhythm to melatonin. It peaks in the morning to promote alertness and gradually declines throughout the day, reaching its lowest level in the evening. This is why a later bedtime can backfire — cortisol starts to rise again, making it harder for your baby to settle.

Research shows that babies who fall asleep earlier at night tend to have lower overall cortisol levels — and that cortisol levels in the day can predict how well they sleep that night.

The 4–5am Challenge

Cortisol starts to rise in the very early hours of the morning, which is why 4–5am wakings are so hard to resolve. Sleep is naturally lighter in these early morning hours, and the body is already preparing to wake for the day. This is not a behaviour problem — it's biology.

Why This Matters for You

• Avoid bright light and screens before bedtime — they suppress melatonin
• A consistent, early-ish bedtime keeps cortisol low at the right time
• Overtiredness raises cortisol, making it harder to settle — not easier

What Is Sleep Pressure?

Think of it like a pressure gauge that fills up while your baby is awake. The longer they're awake, the higher the pressure — and the greater the drive to sleep. When they sleep, that pressure is released and the gauge resets.

The Role of Adenosine

Adenosine is a chemical that builds up in the brain during wakefulness. The more it accumulates, the sleepier you feel. When you sleep, adenosine is cleared — which is why you feel refreshed after a good nap or night's sleep. Caffeine works by blocking adenosine receptors, which is why it temporarily masks tiredness (not that your little one needs any caffeine!).

In Babies

Sleep pressure builds more quickly in babies and young children than in adults. This is why babies need more frequent sleep periods — their pressure gauge fills up faster. This is the biological basis of wake windows.

Two Types of Sleep

NREM (Non-Rapid Eye Movement) sleep is the foundation of restorative sleep. It has three stages, from light to very deep sleep. Deep NREM sleep (Stage 3) is when physical restoration, immune function, and growth happen. Brain waves slow significantly and it's harder to wake a baby from this stage.

REM (Rapid Eye Movement) sleep — also called active or dream sleep — is when the brain is highly active. It's crucial for memory consolidation, learning, and emotional processing. This is why babies (who are learning so much!) spend so much time in REM sleep.

Babies vs Adults

Adults spend roughly 75–80% of sleep time in NREM and 20–25% in REM. Newborns spend close to 50% of their sleep in active (REM-like) sleep — because the developing brain needs it so much. As babies grow, this ratio shifts toward the adult pattern.

Why Babies Wake Between Cycles

A sleep cycle for a baby is typically around 45–50 minutes. Between cycles, there is a brief arousal — a partial waking. Adults generally drift back to sleep without noticing. Babies who haven't yet developed the skill of self-settling will often fully wake at this point and call out for help to return to sleep. This is where sleep associations become important.

What Is SIDS?

Sudden Infant Death Syndrome (SIDS) is the sudden and unexpected death of a baby where no cause is found. While rare, it can happen — and following safer sleep guidance significantly reduces the risk. Around 86% of SIDS deaths occur when a baby is 6 months or younger. Follow safer sleep advice until a baby is 12 months old.

The Key Rules

• Always place baby on their back to sleep — this is one of the most significant changes in infant safety guidance and has dramatically reduced SIDS rates.
• A clear sleep space — no toys, loose bedding, pillows, duvets, bumpers, or positioners in the cot, crib, or moses basket.
• Firm, flat, waterproof mattress — ideally new, not second-hand. No sheepskin, weighted blankets, or wedges.
• Keep the room at 16–20°C — use a baby sleeping bag appropriate for the room temperature.
• No smoking near the baby — before or after birth. Smoking is one of the biggest risk factors for SIDS.
• Room sharing for the first 6 months — safest to have the baby's sleep space in the same room as parents for the first 6 months, for both day and night sleep.
• Never fall asleep with your baby on a sofa or armchair — this is one of the most dangerous situations. If you think you might fall asleep, move to a safe surface first.

On Rolling

When a baby can roll from back to front and back again independently, it's okay to allow them to find their own sleep position. Until they can roll both ways confidently, always start them on their back.

The Official Position

The safest place for a baby to sleep is in their own separate sleep space — a cot, crib, or moses basket — placed in the parents' room for the first 6 months. The guidance does not recommend bedsharing as a routine practice.

When It Happens

Many parents find themselves bedsharing unintentionally — particularly during feeds in the night or early morning. If this is happening, reducing risk is important. The key danger situations to avoid are:

• Falling asleep with baby on a sofa or armchair — this is the highest-risk scenario
• Bedsharing if either parent smokes, has consumed alcohol, or has taken sedating medication
• Bedsharing with very young babies (especially under 3 months) or premature/low birth weight babies
• Sharing a sleep surface with soft bedding, pillows near the baby, or a very soft mattress

Why Darkness Matters So Much

Light directly controls melatonin production. Any light in the room — even a dim nightlight or light peeking around curtain edges — can suppress melatonin and make it harder for your baby to fall and stay asleep. This becomes especially important in the morning hours, when even small amounts of light can trigger early waking.

Making the Room Dark Enough

• Blackout blinds or curtains are one of the highest-value investments you can make
• Cover any LED lights from monitors, plugs, or devices
• Check for light creeping under doors or around curtain edges
• The room should be dark enough that you can't see your hand in front of your face

Daytime Light Exposure

Bright natural light during the day is equally important — it helps set the circadian rhythm, promoting cortisol (wakefulness) at the right time. Get outside with your baby in the morning if you can.

Blue Light & Screens

Blue light (from phones, tablets, TVs) is particularly effective at suppressing melatonin. Avoid screens for at least 30–60 minutes before bedtime, for you and your baby.

The Ideal Room Temperature

The recommended range is 16–20°C (60–68°F). This is supported by Safer Sleep guidelines. If anything, it's better to be slightly on the cooler side — a baby that's too warm is a greater concern from a safety perspective than one that's slightly cool.

Our bodies naturally drop in temperature before falling asleep, which is why even adults struggle to sleep in hot, stuffy rooms.

How to Dress Your Baby

Use a well-fitted sleeping bag appropriate to the room temperature. Good sleeping bag brands publish a temperature guide — typically measured in TOG rating:

Hot Weather Tips

• Keep blinds or curtains closed during the day to stop the room heating up
• A fan in the room (not directly on the baby) can help circulate air
• A bowl of ice in front of a fan creates a cooling effect
• Never use a fan that blows directly onto a sleeping baby

Why White Noise Can Help

White noise masks environmental sounds that might startle or disturb a sleeping baby — traffic, doors closing, older siblings, pets. It can also mimic the constant whooshing sounds heard in the womb, which can be soothing for younger babies.

How to Use It Safely

• Keep the volume at a safe level — roughly equivalent to a shower running (around 50–65 dB) — use a sound level app to check if unsure
• Place the machine or device a reasonable distance from the baby — not right next to their head
• Consistent, steady white noise is better than variable or music-based sounds
• Don't rely on it as a sleep association that must be reproduced throughout the night if you're working on independent settling

Is It Always Necessary?

No — many babies sleep well without it. It's particularly helpful in noisy environments, shared living spaces, or if early morning noise is contributing to early wakings. If it's working well for your family, there's no rush to remove it.

Love & Survival Mode

In those first weeks, it really is about love and survival. Your newborn has a small stomach — this is the key reason they can't sleep longer than a couple of hours; they need regular feeds to meet their nutritional needs.

What's Normal in the Newborn Stage

• Sleeping in short bursts of 1–3 hours, around the clock
• No distinction between day and night — the circadian rhythm isn't developed yet
• Growth spurts causing feeding frenzies followed by quieter spells
• Very inconsistent patterns — this is biologically correct, not a problem to solve
• Grunting, wriggling, and making noises during sleep — this is normal active (REM) sleep

"Le Pause" — Before You Rush In

A key strategy: try not to react immediately when your newborn makes noises or stirs. They often make sounds whilst transitioning between sleep states or trying to settle themselves. Waiting a moment before responding can help them learn to drift back to sleep — and help you avoid waking them unnecessarily.

Contact Napping Is Okay

Holding your baby for naps is absolutely fine in the early weeks. Practise putting them down awake when you have the energy and the opportunity — but don't feel guilty for doing what works right now. Flexibility is key.

Put Baby Down Awake (When You Can)

Practising putting your baby down awake — even drowsy but awake — when the opportunity arises can help them begin to learn the skill of settling to sleep independently. This doesn't mean every single nap from day one. It means building the practice gradually and when it feels achievable.

Differentiate Day and Night

• Keep daytime feeds social and bright — talk to your baby, have natural light in the room
• Keep night feeds calm, quiet, and dark — minimal stimulation, no eye contact if possible
• This helps their emerging circadian rhythm learn that night is for sleeping

A Loose Routine

Rather than a strict schedule, a loose pattern — feed, wake, sleep — can help signal to your baby what comes next. This is a gentle structure, not a rigid timetable.

The Split Feed at Bedtime

This involves splitting the bedtime feed into two parts — with the bath or nappy change in between. This can help your baby take on more milk before bed, which can support a longer first stretch of night sleep. Some families find this really helpful in the early weeks.

Top Strategies for Better Newborn Sleep

• Respond to sleep cues — watch for yawning, zoning out, rubbing eyes
• Don't wait until your baby is fully crying to put them down for sleep
• Try different settling methods — swaddling, shushing, gentle rocking — and see what works for your baby
• Let your partner share the load where possible, especially in the night

These are ranges based on research and clinical experience. Every baby is an individual — these are guides, not targets to stress about.

Signs Your Baby May Need More Sleep

• Fussiness and irritability throughout the day
• Falling asleep during feeds
• Difficulty completing feeds
• Frequent short naps and night wakings
• Rubbing eyes frequently during the day

Wake windows describe the amount of time a baby can comfortably stay awake between sleep periods before sleep pressure builds enough to need sleep again. They are a guide — not a rule — and are based on clinical experience rather than formal research.

The Bedtime Wake Window

The wake window before bed is often the most important one. Too short and the baby won't have built enough sleep pressure to sleep well. Too long and they'll be overtired. For many babies, the final wake window of the day is slightly longer than their typical wake window — but this varies by age and individual baby.

Baby Sleep Cues — Three Stages

🟡 Early Cues (Start the wind-down):

• Zoning out or losing interest in toys or people
• Decreased activity or slower, more disorganised movements
• Tugging at ears or rubbing their face
• Pinkness or flush around the eyes or eyebrows

At early cues: begin transitioning toward the sleep environment and start any wind-down routine.

🟠 Active Cues (Time to settle them now):

• Yawning
• Rubbing eyes
• Becoming more fussy or unsettled
• Pulling faces or grimacing

At active cues: your baby is ready for sleep. Place them in their sleep space now.

🔴 Late Cues (Overtired — act quickly):

• Intense crying
• Arching the back
• Very rigid limbs
• Inconsolable fussiness

At late cues: your baby is overtired. They may need more active settling support to bring down the cortisol response before they can sleep.

Toddler Sleep Cues (Different from babies!)

• Hyperactivity and seemingly "wired" behaviour
• Clumsiness or falling over more than usual
• Emotional outbursts or meltdowns over small things
• Asking for comfort, parents, or a favourite toy more than usual
• Pale or dark circles under eyes

Overtiredness

When a baby stays awake too long past their optimal sleep window, their body responds with a cortisol surge — the stress hormone — to help keep them going. This makes them harder to settle, not easier. An overtired baby often appears "wired," agitated, or inconsolable.

Common signs of an overtired baby or toddler:

• Difficulty falling asleep despite being clearly tired
• Short or fractured naps
• More frequent night wakings
• Earlier-than-usual morning wakings
• Very emotional or reactive behaviour during the day

Undertiredness

Conversely, if a baby is put down for sleep before they've built enough sleep pressure, they may struggle to fall asleep, have short naps, or be difficult to settle. This can happen when nap schedules are too compressed, or when a nap has been too long earlier in the day.

Newborns

A newborn will feed on demand — day and night. This is totally normal and expected. Never reduce feeds for a newborn — this would be a red flag. As babies grow and can take more milk per feed, they often begin to stretch their night sleep naturally.

0–4 Months

Night feeds are still fully expected and necessary. Most babies this age need at least 1–3 feeds overnight. Do not try to reduce or eliminate night feeds at this age.

4–6 Months

Some babies begin to naturally consolidate sleep and may drop to 1–2 night feeds. Others still need 2–3. Responsive feeding remains the approach — feed when your baby signals genuine hunger.

From 6 Months

As solid foods are introduced and milk intake can increase during the day, it becomes more realistic to begin reducing night feeds — but only when the baby is developmentally ready, gaining weight appropriately, and a healthcare professional is supportive. Night weaning is a personal family decision.

Night Feed vs Sleep Association

If your baby always needs a feed to fall back to sleep, and wakes at regular intervals throughout the night regardless of feed timing, they may have developed a feeding sleep association rather than a genuine hunger pattern. This is worth exploring with your sleep consultant.

What Is a Dream Feed?

A dream feed is a feed given to a sleeping or drowsy baby — usually between 10pm and midnight — with the goal of "topping up" their milk intake before the parents go to bed, in the hope of extending the first stretch of night sleep.

Does It Work?

For some families, dream feeds can be very effective at extending that first sleep stretch and giving parents a longer block of sleep. For others, they disrupt the baby's natural sleep cycle and can make waking more frequent rather than less.

How to Do One

• Lift your baby gently without waking them fully
• Offer a breast or bottle — many babies will feed semi-asleep
• Wind gently and replace in their sleep space
• Keep the interaction quiet, dark, and minimal

When to Stop Dream Feeds

Dream feeds are typically most useful under 6 months. Beyond this age, they may start to disrupt night sleep patterns. The weaning process can be gradual — reducing the amount of milk offered over several nights — or more abrupt if the baby is ready.

Is My Baby Ready?

Before reducing night feeds, confirm that your baby:

• Is over 6 months old (ideally older)
• Is gaining weight appropriately
• Is taking solid foods and adequate milk during the day
• Is in good general health
• Your healthcare provider is supportive

Approaches to Night Weaning

Gradual Reduction: Slowly reduce the amount offered at each night feed over 1–2 weeks. For bottle-fed babies, decrease by 1oz every 2–3 nights. For breastfed babies, reduce the duration of each feed gradually.

Eliminating One Feed at a Time: Start with the feed the baby finds easiest to settle without — often the one closest to morning. Once that's gone and baby has adjusted, work on the next one.

Dad or Second Parent Taking Over Night Settling: A different person responding at night can help signal that a feed isn't coming, making the transition smoother for babies who associate the primary feeding parent with nighttime milk.

Why Routines Work

A consistent bedtime routine creates predictability for your baby — a series of familiar steps they come to recognise as the signal that sleep is approaching. This is particularly valuable for babies and toddlers who can't yet understand verbal explanations of what's happening next.

Research shows a consistent bedtime routine has developmental benefits beyond sleep — including language, literacy, and emotional security benefits for the wider family.

What to Include

• Low-stimulation activities — calm play, books, songs
• Bath (if this calms your baby — it energises some)
• Baby massage or lotion routine
• Dim lights for the final 20–30 minutes
• Milk feed (positioned early in the routine to avoid it becoming a sleep association)
• Into the sleep space awake (or drowsy but awake)

Timing & Duration

Aim for a routine of around 30–40 minutes. Some families prefer a longer wind-down — that's fine, as long as it still allows baby to meet their sleep needs. Consistency matters more than the exact steps.

Where to Position the Milk Feed

If you'd like to avoid a feeding sleep association, try to include the milk feed earlier in the routine — before the final wind-down — rather than as the very last step before sleep. This can help separate the act of feeding from the act of falling asleep over time.

Why the Day Shapes the Night

What happens during the day directly affects night sleep. Too much daytime sleep can reduce sleep pressure at bedtime. Too little can result in overtiredness. Consistent daytime nap timing helps regulate the circadian rhythm and set the body clock.

Clock-Based vs Wake-Window Based Routines

Clock-based routines use fixed times for naps and feeds. These are easier to plan around and can work well for babies on 1–2 naps. They require some flexibility around how the baby actually slept the day before.

Wake-window based routines are more responsive — naps follow the baby's last wake time rather than a fixed clock time. These adapt naturally to days when sleep is longer or shorter, and are particularly well-suited to babies on 3+ naps.

Many families combine both approaches — using wake windows as a guide but broadly following a rough clock-based structure.

Morning Wake Time

A consistent morning wake time anchors the whole day's schedule. Even if your baby had a difficult night, trying to keep the wake-up time consistent helps regulate the body clock and makes the rest of the day more predictable.

Why Naps Matter

For children up to around 2–3 years, daytime naps are not optional — they are biologically necessary. Sleep pressure in young babies builds quickly, and naps provide the essential rest that keeps them from becoming overtired and affecting night sleep.

Why Some Babies Only Catnap

Catnaps (30–50 minutes — one sleep cycle) are developmentally normal, particularly in younger babies. Some babies naturally connect sleep cycles and sleep for longer; others do not. Short naps are generally not a problem in the first year and may simply reflect the baby's current developmental stage.

Research tracking over 800 babies showed that nap lengths dip between 1–5 months, then gradually increase after that — continuing right through to around 28 months. There is significant natural variation in nap length between babies.

How Many Naps by Age

A nap transition is when a baby drops from one number of naps to fewer. These transitions can take a few weeks and can temporarily disrupt sleep patterns.

From 3 to 2 Naps

Typical age: 6–9 months (most commonly around 8 months)

Signs it's time: baby is taking longer to fall asleep for the third nap, third nap is short or being refused, or bedtime is being pushed very late to accommodate all three naps.

From 2 to 1 Nap

Typical age: 12–18 months (most commonly around 15–16 months)

Signs it's time: baby is fighting one of the two naps, taking a long time to fall asleep for the second nap, or one nap is very short. The 2-to-1 transition can take several weeks and an "alternate day" approach (1 nap one day, 2 naps the next) can help during this period.

From 1 Nap to No Nap

Typical age: 2.5–5 years (most commonly around 3 years)

This is often a gradual process. Many families find a "quiet time" or "rest time" helpful even when naps stop — this gives both parent and child a break in the day. Some children will still nap if given the opportunity, even if they don't fall asleep every time.

What Is a Sleep Association?

A sleep association is anything a baby or toddler relies on to fall asleep — and then needs reproduced every time they wake between sleep cycles in the night.

Common examples: being rocked or fed to sleep, using a dummy, a parent lying next to them, or being held. When the baby wakes naturally between sleep cycles (which is biologically normal), they find they are no longer in the same conditions as when they fell asleep — and call out for help to re-create them.

Why This Creates Frequent Night Wakings

If a baby is always rocked to sleep, every time they surface between sleep cycles (potentially every 45–90 minutes), they will likely need rocking again to return to sleep. This can mean multiple wake-ups per night that are driven by the association rather than hunger or discomfort.

We All Have Sleep Associations

Adults have them too — most of us fall asleep in a specific position, with certain bedding, a particular pillow. We just don't need someone else to recreate those conditions. The goal is for babies to develop associations they can provide for themselves.

Positive Associations to Encourage

• A comforter or lovey (safe from 6+ months)
• White noise
• A consistent sleep environment (dark, cool room)
• Thumb or finger sucking (once they can do it themselves)

What Sleep Training Is (and Isn't)

Sleep training is the process of helping a baby or toddler learn to fall asleep independently. It is not about forcing a child to sleep, leaving them to cry indefinitely, or withdrawing care and comfort. Gentle methods support a child while gradually stepping back parental involvement.

The Chair Method (Gradual Withdrawal)

The parent sits beside the cot and provides verbal and physical reassurance while the baby falls asleep. Over a series of nights, the chair is gradually moved further away from the cot until the parent is outside the room. This is one of the most gradual and parent-present approaches available.

The Gradual Retreat Method

Similar to the chair method — involves gradually reducing physical presence and comfort over time. The parent might start by lying next to the cot, then sitting beside it, then moving toward the door, then just outside. Progress is made at the baby's pace.

The Fading Method

Gradually fades out the existing sleep association. For example, if a baby needs rocking, the parent gradually reduces the rocking over several nights — rocking until almost asleep, then drowsy, then just calm, until the baby can settle in the cot with just gentle presence. Can also involve switching to a less intrusive association.

Pick Up Put Down (PUPD)

The parent places the baby in the cot awake, provides verbal reassurance, and if baby cries, picks them up briefly to calm (but not to sleep), then places them back down. Repeated until the baby settles. Works well for some babies, but can be stimulating for others — it doesn't suit every child.

What Counts as "Early"?

Typically, any wake time with a 5 in it (or earlier) tends to be considered early — but it depends on your family's rhythm. If your baby goes to bed around 9–10pm on a later schedule, "early" means something different for you.

The Most Common Causes

• Sleep environment: Light creeping in, outside noise picking up (traffic, birds, trains), temperature rising
• Too much daytime sleep leaving insufficient sleep pressure for the full night
• Bedtime too late meaning the baby is overtired and sleep is more fragmented
• Bedtime too early meaning they've simply had enough sleep by 5am
• Developmental milestone or regression temporarily disrupting the morning sleep
• Hunger — particularly in younger or smaller babies

Where to Start (in Order)

1. Check and fix the sleep environment — blackout blinds, white noise, temperature
2. Audit the total 24-hour sleep amount — is daytime sleep too high?
3. Review bedtime timing — is it appropriate for the age and schedule?
4. Check the final awake window of the day — not too short, not too long
5. Consider whether hunger might be a factor

What Is a Sleep Regression?

A sleep regression is when a baby or toddler's sleep is suddenly disrupted — they're harder to settle, waking more, or needing more support. The term "regression" is a misnomer: these periods are almost always driven by a baby's progression — developmental leaps, physical milestones, or big life changes.

Common Causes

• Learning to roll, crawl, sit, pull to stand, or walk
• Language development — their brain is processing new skills
• Growth spurts — increased hunger
• Teething pain
• Illness
• Starting nursery or parent returning to work
• Separation anxiety (peaks at 8–10 months and again at 18 months)
• Change in nap routine
• Desire for independence (especially toddlers)

Common Regression Points

What Is a Split Night?

A split night is when a baby or toddler wakes for a prolonged period in the middle of the night — often 1–3 hours — and is frequently not upset during this time. They may chat, roll around, practice skills, or just lie awake contentedly.

How It Differs from Night Wakings

Frequent night wakings are usually when a baby wakes needing help — a feed, comfort, or support back to sleep. Split nights involve a single long waking, often in the middle of the night, where the baby is content but just not asleep.

Why Split Nights Happen

A split night usually indicates an imbalance between the amount of sleep the baby is getting and what their body needs — most commonly, they're getting too much daytime sleep, so sleep pressure isn't high enough to drive full overnight sleep.

How to Resolve Them

• Review total 24-hour sleep amount — is daytime sleep appropriate for the age?
• Consider capping naps or shifting nap timing to redistribute sleep to the night
• Check whether bedtime is too early for the amount of daytime sleep being had
• Ensure there are no sleep environment issues keeping the baby awake

What Is a False Start?

A false start is when a baby wakes up within 1–2 sleep cycles of falling asleep at bedtime — typically within 45–90 minutes of going down. Many babies do a good first stretch of 2–3 hours even if they wake frequently later, so this first waking is particularly notable.

What Causes Them

• Too much daytime sleep — not enough sleep pressure going into bedtime
• Too short a final awake window — not enough sleep pressure built before bed
• Too long a final awake window — overtired, cortisol spike making it hard to stay asleep
• Bedtime too late — the window of optimal sleep hormones has passed
• Sleep associations — baby wakes and can't resettle without the same conditions

How to Address Them

The investigation should start with sleep needs and schedule — getting the daytime sleep total and the final wake window right. If false starts persist after adjusting the schedule, the focus moves to helping baby develop self-settling skills so they can navigate that between-cycle arousal independently.

The Dummy Dilemma

Dummies (also called soothers, pacifiers, or dodies) are loved and loathed in equal measure — often by the same parents. They can be incredibly helpful, and they can create complications. Understanding both sides helps you make an informed decision.

Potential Benefits

• Can provide genuine soothing and comfort, especially in the early weeks
• The suckling motion can help babies with excess wind or reflux
• Some research suggests dummy use during sleep reduces SIDS risk
• Can help regulate a baby's emotional state during periods of stress

Potential Challenges for Sleep

• If a baby relies on the dummy to fall asleep and can't replace it themselves when it falls out, it becomes a sleep association requiring parental intervention every sleep cycle
• This is the most common "dummy-related" sleep challenge — multiple wakings overnight, not because the baby is hungry or distressed, but because the dummy has fallen out

The Turning Point

Around 6–8 months, many babies develop the fine motor skills to find and replace their own dummy — which resolves the sleep association problem. Some families choose to keep dummies past this point; others prefer to wean off earlier.

The Guidance

Safer sleep guidance recommends room sharing (baby's sleep space in the parents' room) for the first 6 months. After 6 months, it is safe to move your baby to their own room if that's your preference.

Benefits of Moving Them

• Reduces parental disturbance from normal baby noises during sleep
• Gives parents privacy and better-quality sleep
• Can make working on independent settling easier without baby sensing parental proximity

How to Make the Transition Smoother

• Make the new room identical in feel to what they're used to — same white noise, same darkness level, same sleeping bag
• Introduce the room positively during the day before the first night
• Your own smell can be comforting — a recently worn (unwashed) item of your clothing near (but not in) the sleep space
• Be consistent from the first night — going back and forth between rooms can be more confusing

Two Main Approaches

1. The Gradual Approach (4–7 days before)

Shift your baby's schedule by 10–15 minutes every day in the days leading up to the clock change. By the day the clocks change, your baby's body is already adjusted. This is gentler on the body clock and works well for sensitive sleepers.

Clocks going forward (lose an hour): Gradually bring naps and bedtime earlier in the days before.

Clocks going back (gain an hour): Gradually push naps and bedtime later in the days before.

2. The Do-It-In-One Approach

On the day of the clock change, simply follow the new clock times from that morning. There may be a few days of adjustment, but most babies adapt within 3–7 days. This approach requires less planning and works well for adaptable children.

3. The Do-Nothing Approach

Follow your baby's natural body clock and don't adjust at all. Let them guide the new schedule. This works best for babies without rigid routines, or those on very flexible schedules.

When to Make the Move

The most common reason to move a child to a bed is when they start climbing out of their cot — which creates a safety risk. For non-climbers, there is no rush. Many children can comfortably stay in a cot until 2.5–3 years, and keeping them in a cot longer generally supports better sleep containment.

Making the Transition Smoother

• Involve your toddler in choosing bedding or a special pillow — build excitement
• Use a bed guard rail for safety
• Keep the rest of the bedtime routine exactly the same
• Use a toddler clock (Gro Clock or similar) — set it so they know not to get out until the "sun comes up"
• Give clear, calm, consistent boundaries about staying in bed

When They Keep Getting Out

This is extremely common. The key is a consistent, calm response — return them to bed with minimal interaction, every single time. It can take many returns over several nights, but consistency is what makes the boundary stick. Dramatic reactions (positive or negative) can inadvertently reinforce the getting-up behaviour.

The Main Concerns

• The baby waking the older child
• The older child keeping the baby awake or waking them
• Managing different bedtimes in the same space

Practical Strategies

• White noise: A white noise machine can mask sounds between the two children, helping each child sleep through the other's noises
• Stagger bedtimes: Put the older child to bed first (earlier bedtime), then settle the baby once the older child is asleep. Or vice versa — settle the baby first in a quiet period, then bring the older child in when they're ready
• Prepare the older child: Talk to them in advance — explain that the baby might make noise and that's okay, and they don't need to react
• Temporary separation: While working on the baby's sleep settling, temporarily move the older child to a different room for a week or two to avoid disruption

Why Sleep Is Often Affected

Starting nursery or childcare is a significant change in a baby or toddler's world — new people, new environments, different sleep conditions, and separation from primary caregivers. This can manifest as:

• More frequent night wakings as the baby processes the new experiences
• Shorter or refused naps at nursery (different environment, more stimulation)
• Overtiredness from a different sleep schedule during the day
• Increased separation anxiety at bedtime

Supporting the Transition

• Give it time — most babies take 2–6 weeks to fully settle into a new routine
• Communicate your home nap routine to the nursery team where possible
• An earlier bedtime on nursery days can compensate for potentially shorter daytime naps
• Consistent, warm, short goodbyes are better than prolonged or anxious ones
• A familiar comforter (that smells of home) can help your baby feel secure in the new setting

What Is Sleep Apnea?

Sleep apnea in children involves repeated pauses in breathing during sleep, usually caused by upper airway obstruction (obstructive sleep apnea) or less commonly by the brain not sending correct signals to the breathing muscles (central sleep apnea).

Signs to Watch For

• Loud, habitual snoring (on most nights)
• Pauses in breathing followed by snorting or gasping
• Restless sleep — frequent position changes
• Mouth breathing during sleep
• Bedwetting (in previously dry children)
• Daytime sleepiness despite adequate sleep time
• Behavioural difficulties, poor attention, or hyperactivity

What to Do

Sleep apnea in children requires medical assessment — it is beyond the scope of a sleep consultation to diagnose or treat. If you observe these signs, discuss them with your GP or health visitor promptly. Common causes in children include enlarged tonsils or adenoids, which are often treatable.

What Is a Night Terror?

A night terror is a partial arousal from deep NREM (slow-wave) sleep. The child may appear to be awake — screaming, thrashing, eyes open — but is actually still mostly asleep and will have no memory of the event in the morning. They are most common in children aged 2–6 but can occur at any age.

Night Terrors vs Nightmares

How to Respond to a Night Terror

• Don't try to wake them — it can extend the episode and cause more distress
• Stay close and ensure they're physically safe — no risk of falling or hurting themselves
• Speak calmly and softly — even if they don't respond
• Most episodes pass within 5–15 minutes
• They will usually settle back to sleep on their own

What Triggers Night Terrors

• Overtiredness — the most common trigger
• Illness or fever
• Irregular sleep schedules
• Stress or a period of change

When Fears Develop

Nighttime fears are developmentally normal — typically emerging between 18 months and 3 years, as children's imaginations develop and they begin to understand that dangers exist. Common fears include darkness, monsters, being alone, and shadows.

Responding With Empathy (But Not Reinforcing)

Acknowledge your child's fear as real to them — don't dismiss it. At the same time, avoid responses that inadvertently validate and reinforce the fear (e.g. extensive "monster checking" can actually make a child more convinced monsters are a real possibility).

• Validate: "I can hear you're feeling a bit scared. That makes sense."
• Reassure: "You are safe. I am close by."
• Avoid: Elaborate monster-checks, extended stays in the room, or bringing the child into the parents' bed as a fear response — these can inadvertently increase anxiety over time

Practical Strategies

• A dim night light (red or warm tone) can provide reassurance without significantly impacting melatonin
• A comforter or "protector toy" can be empowering for the child
• Books about brave characters, or stories that normalise night fears, can help
• A predictable, calm bedtime routine reduces anxiety by creating certainty
• Toddler clocks (like the Gro Clock) can give children a concrete visual cue for when it's okay to call out or leave their room

During the Illness: Comfort First

When your baby or toddler is unwell, the goal shifts from sleep habits to comfort and recovery. This is not the time to hold firm on settling methods or worry about undoing progress. A sick child needs more support — and that's completely appropriate.

• Let them sleep more if they need it. Illness increases sleep need. Extra naps, earlier bedtimes, and longer overnight sleep are all normal and helpful.
• Offer more comfort. Feeding, holding, and extra contact at night is fine. This will not permanently undo settled sleep habits built over weeks.
• Keep the bedtime routine the same where you can. Even if everything else shifts, a familiar bedtime sequence gives comfort and signals that normal life is still there.
• Expect more night wakes. Discomfort, congestion, or fever will disturb sleep — this is temporary. Respond calmly, offer reassurance, and don't worry about frequency.
• Prioritise fluids. A sick baby may need additional feeds overnight for hydration — follow your instincts and your healthcare provider's advice.

After the Illness: Getting Back on Track

This is where families often panic unnecessarily. A week of poorly sleep during illness does not erase months of progress. Sleep skills don't disappear — they just need a little re-practice.

Once your baby has been well for 24–48 hours:

• Return to your normal bedtime routine from the very first night back
• Go back to your usual settling approach — or one small step back from it if things feel very disrupted
• Allow 2–3 nights for sleep to resettle before expecting to be back to where you were
• Don't introduce new habits during the illness that you'll then need to unpick (e.g. if your baby was managing without a dummy, try not to reintroduce it during the illness)

You Don't Need to Recreate Home Perfectly

The aim is to protect the non-negotiables — not to replicate every detail of your home sleep environment. Flexibility during travel is fine, and most babies adjust much more quickly than parents expect.

The Non-Negotiables to Pack

• Darkness. A portable blackout blind is one of the best travel investments you can make. A poor sleep environment is the most common cause of disrupted sleep away from home — and the most fixable. Use rolled towels or clips to seal gaps around curtains if needed.
• White noise. A white noise app on your phone or a small machine helps mask unfamiliar sounds in hotels, family homes, or rental properties.
• Your bedtime routine. The routine is your portable anchor. Wherever you are, the same sequence of steps — bath, feed, book, song, into the cot — tells your baby's brain that sleep is coming. This is more powerful than any sleep environment.
• A familiar comforter or lovey. Anything that smells of home and feels familiar provides security in a new environment.
• Your sleep phrase. Whatever you say to your baby at bedtime — use it consistently. Familiar language is comforting.

If Naps Need to Happen on the Go

• Pram, car, or contact naps during travel are absolutely fine — treat them as naps and count them in your day total
• If naps are shorter than usual on travel days, bring bedtime earlier that evening
• Don't stress about perfection during the outward journey — prioritise settling in to the destination first

Time Zones

For short trips of 1–2 hours' time difference, it's often easier to keep your baby roughly on home time rather than adjusting fully. For longer differences, aim to shift by 15–20 minutes per day in the days before you travel (if you have time), or adjust on arrival and allow 3–5 days to settle. Early morning outdoor light exposure is the fastest way to help your baby's body clock adjust.

When You Get Home

Return to your normal routine from the first night back — same bedtime, same settling approach, same nap structure. Most babies re-adjust within 3–5 nights, often faster than that. If sleep is bumpy on return, hold your nerve and stay consistent — your baby will find their rhythm again.

Does Teething Really Disrupt Sleep?

Teething is one of the most commonly cited reasons for disrupted baby sleep — and also one of the most over-attributed causes. The honest answer: teething can and does cause genuine discomfort, and that discomfort can temporarily disrupt sleep. However, it is rarely the sole explanation for prolonged or severe sleep difficulties.

Research suggests that actual teething pain is most acute in the 3–4 days around a tooth breaking through the gum. Persistent poor sleep over weeks or months is unlikely to be caused by teething alone.

Signs of Genuine Teething Discomfort

• Increased drooling
• Chewing on hands, toys, or anything they can reach
• Swollen, red gums (you may be able to feel a tooth under the surface)
• Mild temperature (teething can cause a slight rise in temperature, but a high fever is not caused by teething — seek medical advice if your baby has a fever)
• Fussiness and irritability, particularly in the late afternoon and evening when discomfort often peaks
• Disrupted sleep for a few nights around the time a tooth visibly appears

How to Help

• Cold teething toys — chilled (not frozen) teethers can provide numbing relief on the gums
• Chilled fruit or veg in a mesh feeder — for babies on solids, this can provide relief and distraction
• Gentle gum massage — a clean finger rubbed along the gum line can provide short-term relief
• Pain relief — infant paracetamol or ibuprofen (following age-appropriate dosing instructions) can be appropriate for genuine teething discomfort, particularly at bedtime. Always follow dosing guidance and consult your pharmacist or GP if unsure.
• Teething granules or gels — check ingredients carefully; products containing lidocaine are not recommended for babies

Protecting Sleep During Teething

• Keep the bedtime routine the same — structure is soothing during discomfort
• Offer appropriate pain relief before bed if your baby seems uncomfortable
• Respond calmly to night wakes — extra reassurance is appropriate, but try to return to your usual settling approach once comfort is given
• Give it 3–4 days. If sleep normalises once the tooth is through, teething was likely the cause

The Most Important Question First

Before thinking about reducing night feeds, the key question is: is my baby waking from genuine hunger, or has feeding become a sleep association? The answer changes the approach entirely.

Signs of Genuine Hunger

• Baby feeds actively and well when offered — not just suckles briefly and drifts off
• After feeding, they settle back to sleep fairly easily and sleep a reasonable stretch
• The timing of wakes roughly corresponds to the expected feed interval for their age
• Baby is young (under 6 months) or going through a growth spurt
• Milk intake during the day seems insufficient for their age and weight

Signs of a Feeding Sleep Association

• Baby always needs a feed to fall asleep — at bedtime and at night wakes
• Wakes occur frequently and at irregular intervals regardless of feed timing
• The feed is short — baby takes a small amount and immediately falls back to sleep
• Baby is over 6 months, taking good solid feeds during the day, and gaining weight well
• Waking pattern is very predictable, often at the same times each night

Night Feeds by Age: What's Expected

When You're Ready to Reduce Night Feeds

There is no obligation to reduce night feeds until you and your baby are both ready. When you are ready, here are the approaches:

Gradual reduction: For bottle-fed babies, reduce the amount offered at each feed by 1oz every 2–3 nights until the feed is small enough to drop. For breastfed babies, reduce the duration of the feed by 1–2 minutes every couple of nights.

Eliminate one feed at a time: Identify the feed your baby seems least interested in — often the one closest to morning. Respond to that wake with your usual settling approach instead of a feed. Once that's resolved (usually 3–5 nights), move to the next feed.

Second parent or partner takes night settling: If a baby is strongly associated with feeding from one parent, having the other parent respond to night wakes can be very effective. The baby quickly understands that a feed isn't coming from this person, and often settles more readily.

Maximise daytime milk intake: Before reducing night feeds, make sure your baby is taking as much milk as possible during the day. A baby who's hungry will be much harder to settle at night without a feed.

At this age your baby is typically on three naps — two longer naps and a short late-afternoon "power nap" to bridge to bedtime. Many babies are also beginning to explore solid foods alongside milk.

By 9–10 months most babies have transitioned to two naps. Wake windows have stretched to around 3 hours, allowing for a more structured and predictable day with longer gaps between sleeps.

Between 11–14 months the morning nap shortens naturally as wake windows extend. The afternoon nap carries the bulk of daytime sleep, with the morning nap acting more as a short bridge. Many babies begin transitioning to one nap toward the end of this period.

Once on one nap, the day structure simplifies significantly. The single midday nap carries all daytime sleep, and wake windows either side are long. This routine works from around 14–15 months right through to when the nap is dropped — often between 2.5 and 3 years.
