Sleep in school-age children
Busy brains, late bedtimes and the worry hour.

What's going on?
School-age children need roughly 9–12 hours of sleep a night. Most get less, and the effects show up as mood, behaviour and concentration long before the child says they are tired.
At this age, the biggest sleep disruptors change. Toddler-style resistance gives way to a busy brain: worries about the day, replaying friendship trouble, thinking about tomorrow's test. Bedtime is often the first quiet moment a child has had all day, and worry fills it.
Light and stimulation matter more now too. Devices, homework and after-school clubs push the natural sleep window later, while school start times stay the same.
Common signs and symptoms
Very common
- Taking a long time to fall asleep while lying awake thinking.
- Coming downstairs repeatedly with questions and worries.
- Hard to wake in the morning, sluggish and irritable.
- Emotional fragility and short fuse late in the day.
- Catching up dramatically at weekends.
Less common
- Waking in the night and being unable to get back to sleep.
- Nightmares or night terrors several times a week.
- Snoring, gasping or pauses in breathing.
- Falling asleep in the day.
Loud snoring with pauses in breathing is not just noisy sleeping — it warrants a GP appointment, as sleep apnoea in children causes daytime behaviour and concentration problems.
Is this normal?
Some difficulty settling is very common, particularly at times of change, and usually settles within a couple of weeks with a consistent routine.
Worry at bedtime is close to universal in anxious children. It isn't a sleep problem so much as an anxiety problem showing up at the quietest moment of the day.
Practical things that help
Same wake-up time every day, including weekends
The body clock is anchored by wake time far more than by bedtime.
A wind-down that starts 45 minutes before lights out
Dim lights, no screens, quiet activity. The brain needs a runway, not a cliff.
Devices out of the bedroom overnight
Removes both the light and the temptation, and is consistently the change that helps most.
Have the worry conversation earlier
A 10-minute 'worry time' after tea, with a notebook, stops worries queuing up for bedtime.
Keep the last 20 minutes connected
Reading together, chatting in the dark. Connection settles the nervous system better than any routine chart.
Check the room
Cool, dark and quiet. Blackout blinds in summer make a real difference in the UK.
Watch the caffeine
Cola, iced coffee drinks, energy drinks and chocolate late in the day are common hidden culprits at this age.
Daylight and movement in the morning
Bright light early sets the clock so melatonin rises at the right time in the evening.
Return them calmly and briefly
Fewer words, same response every time. Boring is the goal.
What can accidentally make it harder?
A later bedtime because they're not tired
Overtiredness makes settling harder, not easier — cortisol rises and the child gets a second wind.
Big emotional conversations at lights-out
It's the only time they'll talk, which is exactly why it becomes a stalling tactic and a worry amplifier.
Screens in the last hour
Light and stimulation both delay the sleep signal.
Very long, elaborate routines
A 90-minute wind-down gives 90 minutes of opportunity to negotiate.
Lying with them until they're asleep, most nights
It works beautifully in the moment and can become the only condition under which sleep is possible.
These are gentle observations, not blame. None of us avoid all of them all of the time.
What should I say?
- “Worry time is after tea. Write it in the book and we'll deal with it then.”
- “It's sleep time now. I'm just downstairs.”
- “You don't have to fall asleep. You just have to stay in bed and rest.”
- “Same answer as last time. Back to bed, love.”
- “Tell me one good bit and one hard bit of today, then lights out.”
Red flags and when to seek help
Worth an assessment
- Snoring with gasping or pauses in breathing.
- Excessive daytime sleepiness, or falling asleep in class.
- Sleep problems persisting for months despite a consistent routine.
- Night terrors or nightmares several times a week.
- Restless, jerking legs, or a strong urge to move the legs at night.
- Sleep disruption alongside low mood, anxiety or a drop at school.
Urgent — same day
- Sleep loss alongside talk of self-harm or hopelessness.
Emergency — call 999
- Long pauses in breathing with colour change — seek immediate medical help.
Your GP can assess for sleep apnoea, restless legs and anxiety, and refer where needed. School nurses can help with routines. The Sleep Charity (thesleepcharity.org.uk) has a national helpline and free guides for families.
If your child is seriously unwell or in danger, get help now.
Common myths
- Myth: a later bedtime means they'll sleep better. Overtiredness usually makes settling worse.
- Myth: they can catch up at the weekend. Lie-ins shift the body clock and make Monday harder.
One tiny next step
Tonight, set a charging station outside the bedrooms and move the worry conversation to after tea.
