Sleep Routines for School: What Time Should My Child Go to Bed?

My School Agent | 8 July 2026

I once let my son stay up to watch the end of a film on a school night. It finished at 9:30pm. He was seven. The next morning was horrific. He cried putting his shoes on. I had created a monster through poor planning and Disney.

Sleep is the thing you don't value until it's gone. Children who don't sleep enough struggle at school. They're irritable, unfocused, and emotional. You're irritable, unfocused, and emotional trying to get them out the door. Here's how much sleep they actually need.

NHS Recommended Hours by Age

The NHS publishes clear guidance on how much sleep children need:

  • 3-5 years (Reception): 10-13 hours
  • 6-12 years (Primary): 9-12 hours
  • Teenagers: 8-10 hours

Most primary age children need 10-11 hours. Some need more. Very few need less.

A five-year-old needs 11 hours. A nine-year-old needs 10 hours. If your nine-year-old goes to bed at 9pm and wakes at 6:30am, they're getting 9.5 hours. That's not enough.

Work Backwards From Wake-Up Time

Figure out what time your child needs to wake up for school. Add 30 minutes for the faff of actually getting them out of bed. That's your target wake-up time.

Now subtract the hours of sleep they need. That's bedtime. Not the time they go upstairs. The time they're actually asleep.

Example: your seven-year-old needs to wake at 7am. They need 10.5 hours of sleep. That means asleep by 8:30pm. If bedtime routine takes 30 minutes, you start at 8pm.

Most parents are shocked when they do this maths. Bedtime suddenly becomes much earlier than they thought.

The Screen Before Bed Problem

Screens before bed delay sleep. Blue light suppresses melatonin, the hormone that makes you sleepy. A child watching a tablet at 7:45pm won't fall asleep easily at 8pm.

Cut screens at least an hour before sleep. Yes, that includes homework on the iPad. Finish it earlier.

This is the rule everyone breaks. Try anyway. Even 30 minutes of screen-free wind-down helps.

A Bedtime Routine That Works

Children sleep better with a predictable routine. It signals to their body that sleep is coming.

A simple routine:

  1. Screens off
  2. Bath or wash
  3. Pyjamas on
  4. Brush teeth
  5. Story or chat in bed
  6. Lights out

This takes 30-45 minutes. Do it in the same order every night. Consistency is what makes it work.

Stories are optional but helpful. Ten minutes of calm reading settles children. Audiobooks count if you're too tired to read aloud.

What If They Won't Sleep

Some children fight bedtime. They're not tired. They want one more story. They need water. They heard a noise.

This is normal. It's also exhausting.

For younger children (Reception to Year 2): Stay calm. Return them to bed without engaging. No conversation, no negotiation. Just "it's bedtime" on repeat. This takes a week of consistency before it improves.

For older children (Year 3+): Set expectations earlier in the evening. "Bedtime is 8pm. After that, stay in your room. You can read quietly but don't come out unless it's an emergency."

Some children genuinely aren't tired at the time you want them to sleep. If your child is lying awake for an hour every night, bedtime might be too early. Adjust by 15 minutes and see what happens.

The September Reset

Sleep routines collapse over summer. By September, children are staying up late and sleeping in. The first week of term is carnage.

Start shifting bedtime earlier a week before school starts. Move it 15 minutes earlier every few days. By the first day of term, they're back on track.

This also applies after Christmas and Easter holidays. Any break longer than a week needs a reset.

Why Tired Children Struggle at School

Tired children can't focus. They fidget. They forget instructions. They cry over small things. Teachers notice.

Chronic tiredness affects learning. A child who is behind on sleep all term will underperform compared to their ability. It's not about being clever. It's about having the energy to concentrate.

Sleep is the cheapest intervention you can make for school performance. More effective than tutoring. Definitely more effective than extra homework.

What About Weekends

Let them sleep in a bit on weekends. An extra hour is fine. Two hours starts to mess with their body clock.

If your child sleeps until 10am on Saturday, they won't be tired at their usual bedtime Saturday night. By Sunday night, bedtime is a battle. Monday morning is rough.

Keep weekend wake-up times within an hour of school days if you can. Yes, this is miserable for you. It does make Monday easier.

When Sleep Problems Are More Than Routine

If your child is getting enough hours but still tired all day, talk to your GP. Sleep disorders exist. Snoring, restless legs, anxiety can all disrupt sleep quality.

Most of the time, it's just not enough hours. But if you've fixed that and nothing has changed, get it checked.

If keeping track of bedtime routines alongside early-morning clubs and late pickups feels impossible, I built My School Agent to map out your week before it ambushes you. It won't send your child to sleep, but it'll remind you when tomorrow is early PE.
