Toddler Sleep Guide UK.
Naps, bedtimes & what changes.
How toddler sleep differs from baby sleep, how much they need at every age, sample schedules, the nap transition, early waking, bedtime resistance and the most common problems — with honest, practical fixes.
This guide covers toddler sleep from age 1 to approximately 5 years. For baby sleep (birth to 12 months), see our baby sleep guide. For sleep training approaches applicable to toddlers, see our sleep training methods guide.
How much sleep toddlers need
Toddler sleep needs reduce gradually across the 1–5 year period. Night sleep stabilises and lengthens, while daytime napping reduces from 1–2 naps to none. The ranges below are wide — individual variation is significant and both ends of the normal range are fine.
| Age | Total sleep / 24h | Night sleep | Naps | Bedtime |
|---|---|---|---|---|
| 12–15 months | 12–14 hrs | 10–12 hrs | 1–2 (transitioning) | 6:30–7:30pm |
| 15–18 months | 12–14 hrs | 10–12 hrs | 1 (after transition) | 6:30–7:30pm |
| 18 months–2 years | 11–14 hrs | 10–12 hrs | 1 (1–2 hrs) | 7–8pm |
| 2–3 years | 11–13 hrs | 10–12 hrs | 1 or 0 | 7–8pm |
| 3–5 years | 10–13 hrs | 10–12 hrs | 0 (some still nap) | 7–8:30pm |
Sample schedules by age
The 2-to-1 nap transition
Most toddlers transition from 2 naps to 1 nap between 12 and 18 months — typically around 14–15 months, though some make the shift earlier or later. The transition is often bumpy and takes 4–6 weeks before a new pattern consolidates.
Signs a toddler is ready for 1 nap
Consistently resisting the morning nap, or taking so long to fall asleep that the nap shifts later and later. Taking the morning nap but then fighting the afternoon nap entirely. Napping in the morning and then unable to fall asleep at bedtime until very late. Being able to stay awake through to midday without obvious distress on most days.
How to manage the transition
Gradually push the morning nap later — from 9:30am to 10am to 10:30am to 11am — over the course of 1–2 weeks until it has shifted to around noon. During the transition, an earlier bedtime (6–6:30pm) prevents the cumulative overtiredness that derails settling. Expect some difficult days — mood and sleep quality during the transition are often worse before they improve.
Common toddler sleep problems
Early waking is one of the most common and most difficult toddler sleep issues. It is almost always caused by one of four things: bedtime is too late (overtiredness causes early waking — counterintuitive but consistent); the nap is ending too late and reducing sleep pressure at night; the sleep environment gets light early; or the child is genuinely a natural early waker.
Fix attempts in order: try moving bedtime 15–30 minutes earlier (not later). Ensure blackout blinds are genuine blackout — even a small amount of early morning light triggers waking in light-sensitive children. Cap the afternoon nap so it ends by 3pm. If none of these help after 2 weeks of consistency, the child may simply wake early — a toddler clock (the “okay to wake” light) can help teach that 6am is the start of the day even if the child wakes before it.
Toddlers are developmental experts at stalling — one more drink, one more story, one more wee. The fix is a consistent, predictable routine that meets all reasonable needs proactively before they become requests. Bath, pyjamas, milk, one story, one song, lights out. Pre-empt: “before I leave, do you need water? One last hug?” Once you’ve left, don’t return for non-urgent requests.
For children who repeatedly leave their room, a clear and consistent consequence applied immediately is more effective than negotiation. The “hall pass” system — giving a child one physical token per night that they can use to “buy” one extra request — works well for some families, giving the child agency while limiting the endless stalling.
Night waking in toddlers who were previously sleeping through is usually triggered by developmental changes (a leap or regression), illness, separation anxiety, or a change in routine. The 18-month regression and the 2-year regression are well-documented and typically last 2–6 weeks. Maintain the routine, respond calmly, and avoid introducing new sleep associations (feeding to sleep, bringing into the parental bed) that will need to be phased out again.
If a toddler is waking and calling out but not distressed, a brief check-in with minimal interaction is usually sufficient. If night waking is caused by nightmares (more common from age 2–3), brief comfort followed by returning to bed — rather than a long settle — is the goal.
A toddler consistently taking very short naps (under 45 minutes) is usually either not tired enough at nap time — in which case move the nap slightly later — or is waking between sleep cycles and not able to resettle. For the latter, consistent earlier intervention (going in before full waking and resettling) can help consolidate naps over 2–3 weeks. After age 2.5–3, short naps may indicate the child is moving toward dropping the nap rather than a fixable problem.
Dropping the nap entirely
Most children drop their nap between ages 2.5 and 4 years — the average in the UK is around 3 years, but significant individual variation is normal. Some children continue napping until 5; others drop the nap at 2. The nap should be dropped when the child consistently fails to fall asleep within 30 minutes at nap time AND is falling asleep well at the adjusted earlier bedtime — not because they refuse it once or twice.
When the nap is dropped, move bedtime earlier immediately — often by 30–60 minutes. A child who was napping until 3pm and going to bed at 7:30pm will likely need a 6:30–7pm bedtime without the nap. Resist the urge to keep bedtime late to compensate. Earlier bedtime does not produce earlier waking — it typically produces the same wake time or later, and a better-rested child overall.
Even if the child is not sleeping, a daily quiet time (books, audiobooks, calm play in their room) of 45–60 minutes at the former nap time preserves parental sanity and gives the child’s brain valuable rest time.
Sleep environment — cot to bed transition
Most children move from a cot to a toddler bed or single bed between ages 2 and 3. There is no single right time — the transition is usually triggered by the child climbing out of the cot (a safety issue), a new sibling needing the cot, or the child asking to move to a “big bed.”
Making the transition work
If possible, keep everything else the same — same room, same routine, same bedding where possible. The bed itself should be the only change. A bed guard or floor mattress prevents falls in the first few weeks. The most common challenge is that a toddler who can now get out of bed independently will test this thoroughly — respond to returns to the room calmly, consistently and with minimal interaction. The novelty usually passes within 2–3 weeks.
For the sleep environment more broadly: blackout blinds are highly effective for early waking and nap quality. See our best blackout blinds guide. White noise remains useful for toddlers if already established — there is no evidence it needs to be phased out. Room temperature between 16–20°C is recommended.
Most toddler sleep problems have practical fixes. Consistency is the active ingredient in almost all of them.
Toddler sleep is considerably more manageable than newborn sleep, but the developmental changes — nap transitions, regressions, the move from cot to bed, the dropping of the nap — mean it rarely stays settled for long before something changes. The core principles don’t change: consistent routine, age-appropriate schedule, dark room, calm response to problems.
The single most underrated lever in toddler sleep is bedtime. Moving bedtime earlier — even by 30 minutes — improves settling, reduces night waking and does not produce earlier waking. If something isn’t working, try earlier bedtime before trying anything else.
