What time should a 4 year old go to bed?

Last reviewed: 14 September 2026

Four is the year most children drop the nap for good and, in the UK, start Reception. Both change what bedtime needs to be.

Bedtime chart for a 4-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 4-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 4-year-old need?

A 4-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.

Starting school changes the maths

In England, children start Reception in the September after they turn four, which means a large share of 4-year-olds are doing a full school day while still technically preschoolers by every sleep guideline. That combination — no nap, six hours of school, and a body that still needs up to 13 hours — is why the autumn term is so notoriously brutal.

The useful move is to bring bedtime forward before term starts, not after. Two weeks out, shift bedtime and wake-up 10 to 15 minutes earlier every three days until you land on the school-morning time. Doing it gradually works because the body clock shifts at roughly that pace; doing it in one jump on the first Sunday usually produces a fortnight of 5:30 AM wake-ups.

Expect the first half-term to need an earlier bedtime than the summer holidays did — often 30 minutes earlier. Many parents assume a school-aged child needs less sleep and move bedtime the wrong way.

Nightmares and the dark

Four is the peak age for a sudden fear of the dark, and for nightmares that the child can now describe in detail. This is developmental, not a sign anything is wrong — imagination arrives before the ability to tell the imagined from the real. A dim red or amber night light, a door left ajar, and taking the fear seriously rather than arguing it away all help. Nightmares happen in the second half of the night, in REM sleep, so a child who wakes distressed at 2:00 AM is usually having one; night terrors, which look far worse and which the child will not remember, happen much earlier in the night instead.

Signs a 4-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.

• falls asleep on the sofa before dinner, or in the car on the way home from school
• the late-afternoon crash between 4:00 PM and 5:30 PM is getting louder
• needs waking every school morning but sleeps in at weekends
• behaviour at school dips as the week goes on and recovers over the weekend

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 four

Keep it to 25 or 30 minutes and finish in the bedroom, not the living room. At four, children can follow a picture routine chart, and letting them tick the steps off shifts a surprising amount of the argument from you to the chart.

This is a good age to introduce a short chat about the day — two minutes, one good thing and one hard thing — at the start of the routine rather than at lights-out. It gets the day's worries out while there is still time to deal with them, instead of at the point where you want them to stop talking.

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.
