What time should an 8 year old go to bed?

Last reviewed: 14 September 2026

Eight is when screens in the bedroom start being asked for, and when the answer you give sets the pattern for the next five years.

Between 7:30 PM and 8:45 PM

Most 8-year-olds should be asleep between 7:30 PM and 8:45 PM. For a 7:00 AM wake-up, aim for lights out at about 8:15 PM, giving around 10½ hours.

Eight-year-olds need 9 to 12 hours a night. Nine hours is the floor, not the target — a child sleeping nine hours flat every school night has no margin for a late finish or a bad night.

Bedtime chart for an 8-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 8-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 an 8-year-old need?

An 8-year-old needs 9 to 12 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.

The useful test

Ranges are guidance; your child is the evidence. An 8-year-old getting enough sleep wakes without being called, is reasonably civil before breakfast, and does not need a long lie-in at weekends to function. If all three are true, you have the right bedtime.

The device question, and why the bedroom answer matters

Eight is roughly when a tablet or a console in the bedroom stops being unthinkable and starts being asked about. The research on screens and children's sleep is messier than headlines suggest — the blue-light effect is real but modest at typical screen brightness. The much larger effect is simply displacement: time on a device is time not spent asleep, and content designed to be hard to stop is hard to stop at 8:00 PM.

The practical line that holds up best over the following years is that devices charge overnight outside the bedroom, for everyone in the house including the adults. Framed as a house rule rather than a punishment, it is far easier to maintain at eight than to introduce at thirteen, when the same rule reads as a withdrawal of trust.

Sleepovers start

Sleepovers arrive around this age and they cost real sleep — typically three to four hours on the night, plus a scrambled body clock the next day. That is fine occasionally. The thing worth planning is the day after: a deliberately quiet Sunday and a normal bedtime, rather than an early one, since an over-early bedtime after a short night often produces a 5:00 AM waking and a worse Monday.

Signs an 8-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.

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 eight

Fifteen to twenty minutes of routine plus a reading window. At eight most of the work is in the boundaries around the routine rather than the routine itself — a fixed screens-off time, a fixed lights-out, and a bedroom that does not contain the things they would rather be doing.

If your 8-year-old resists a set bedtime, involving them in working out the arithmetic is surprisingly effective: show them the wake-up time, the hours they need, and let them see the answer come out. A conclusion they helped reach gets less resistance than an instruction.

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.

Where these figures come from. Sleep duration recommendations are taken from the American Academy of Sleep Medicine’s consensus statement on sleep for healthy children, the National Sleep Foundation’s duration recommendations, and UK guidance from The Sleep Charity.

Common questions

What time should 8 year olds go to bed?

Between 7:30 PM and 8:45 PM depending on the morning. For a 7:00 AM wake-up, 8:15 PM lights out gives about 10½ hours.

How much sleep do 8 year olds need?

9 to 12 hours a night according to the American Academy of Sleep Medicine. Most 8-year-olds do best on 10 to 11 hours; nine hours is the bottom of the healthy range rather than a target.

What time should an 8 year old go to bed?

Between 7:30 PM and 8:45 PM depending on the wake-up time. For a 7:00 AM start, 8:15 PM lights out gives about 10½ hours.

Should an 8 year old have a phone or tablet in their bedroom at night?

The evidence points firmly towards no — mainly because of displaced sleep rather than blue light. A whole-house rule that devices charge outside bedrooms overnight is much easier to establish at eight than at thirteen.

Is 9pm an acceptable bedtime for an 8 year old?

It gives about 9¾ hours before a 7:00 AM wake-up, which is inside the range but towards the bottom. It works if your child wakes easily and is cheerful in the morning; if they are hard to rouse, pull it back by half an hour.
