What time should a 3 year old go to bed?

Last reviewed: 14 September 2026

Three is the age when the afternoon nap starts to wobble and the bedtime battles begin. Here is what the guidelines actually say, and what bedtime that works out to for a normal morning.

Bedtime chart for a 3-year-old

Find the time your child has to be up, and read across. These bedtimes are lights out, not the start of the evening — they already include about 15 minutes to fall asleep, which is a typical figure at this age.

If your 3-year-old wakes on their own at roughly the right time and is cheerful for the first twenty minutes of the day, the bedtime you are using is working. If they need waking every morning, it is too late — whatever the chart says.

How much sleep does a 3-year-old need?

A 3-year-old needs 10 to 13 hours of sleep a night. The major guidelines agree closely, and all of them give a range rather than a number because healthy children genuinely vary by an hour or more either side.

Naps are the reason 3 is confusing

This is the only age on this list where the answer genuinely depends on the afternoon. Around two-thirds of 3-year-olds still nap, and the guidelines count that nap towards the daily total. A child who sleeps 75 minutes after lunch and then goes down at 7:00 PM is being asked to sleep 13 hours in 24 — the very top of the range — and will often lie awake for 45 minutes, which parents read as a bedtime problem when it is really a nap problem.

The practical rule: for every hour your 3-year-old naps, push bedtime about 45 minutes later. That is not a precise formula, but it stops you fighting the wrong battle. If bedtime is dragging past an hour, the nap is usually the first thing to shorten — cap it at an hour and wake them by 2:30 PM — before you try moving bedtime.

Dropping the nap entirely is rarely clean. Most children go through a few months where they need it on some days and not others. On no-nap days, bring bedtime forward by 30 to 45 minutes rather than pushing through to the usual time; an overtired 3-year-old gets harder to settle, not easier.

The move from cot to bed

Most families make this move somewhere between 2 and 3½. It almost always costs you a few weeks of worse sleep, because a bed is an exit and a cot (or crib) is not. Expect the wandering. A very boring, near-silent walk back to bed — every time, no conversation — usually resolves it faster than anything else, because the attention is what is being tested.

Signs a 3-year-old is not getting enough sleep

Tiredness in children rarely looks like tiredness. It is far more likely to arrive as behaviour, and the timing is the giveaway — it clusters in the late afternoon and gets worse as the school week goes on.

• needs waking most mornings, or is very hard to rouse
• falls asleep in the car on short journeys
• meltdowns that escalate sharply from about 5:00 PM
• an early-morning waking before 5:30 AM — often a sign of an overtired, not under-tired, child

Snoring every night, long pauses in breathing, or persistent mouth-breathing during sleep are different — those are worth raising with your GP rather than treating as a bedtime problem.

A bedtime routine that works at three

At three, the routine matters more than the exact clock time, because the sequence is what tells a child sleep is coming. Twenty to thirty minutes is plenty: bath, teeth, pyjamas, two books in a dim room, same song or phrase, out. Keep the order identical every night — three-year-olds are ferocious about order and will use any variation as a negotiating opening.

A single, named comfort object helps enormously at this age. So does a "one more thing" allowance built into the routine on purpose — one extra sip of water, placed at the end — because it satisfies the urge to extend without opening a negotiation.

How to move bedtime earlier without a fight

1. Fix the wake-up time first. Same time every day, weekends included, for a week. A stable morning anchors the body clock far more effectively than a stable bedtime does.
2. Move in 15-minute steps. Shift lights out 15 minutes earlier every three or four nights. The body clock will follow that; it will fight an hour.
3. Get daylight into the morning. Curtains open on waking, and ten to fifteen minutes outside before school if you can manage it.
4. End screens before the wind-down starts, not as part of it — stopping something engaging is itself stimulating.
5. Give it a fortnight. Two or three nights tells you nothing. Judge it by how the mornings look after two weeks.
