Key takeaways

1. Why this weekend

The clocks went back an hour at 2am on Sunday 25 October, the weekend half-term began for many schools. A week of later nights and lie-ins on top of that can leave children wide awake at bedtime and groggy on Monday morning.[1]

The last weekend of half-term is the easiest time to put that right, before early alarms and homework come back.

2. How much sleep children need

The American Academy of Sleep Medicine recommends 9 to 12 hours a night for children aged 6 to 12, and 8 to 10 hours for teenagers aged 13 to 18. Younger children, aged 3 to 5, need 10 to 13 hours including naps.[2]

In adolescence the body clock shifts later, so teenagers naturally feel sleepy later at night. Their need for sleep hardly drops, but school still starts early. That is why holiday lie-ins can turn into a jet-lagged Monday.[4]

3 to 5 years

13 to 18 years
8 to 10 hours

3. Why sleep matters for learning

While we sleep, the brain replays the day and strengthens new memories, linking them to what we already know. Research reviews show that sleep after learning helps that learning last.[3]

So an hour lost to a late night isn’t just tiredness the next day. It can cost some of what your child learned earlier, which matters with mocks and tests coming up this term.

Sleep is revision you do in bed.

4. Five resets for the last weekend

Small, steady changes work better than ordering an early night on Sunday and hoping for the best.[6]

Fix the wake-up time

Pick Monday’s alarm time and use it on Saturday and Sunday too. A steady wake-up time anchors the body clock.

Let the daylight in

Open the curtains straight away and get outside in the morning, even for a short walk.

Move bedtime in small steps

Bring bedtime about 15 minutes earlier every couple of nights, rather than one big jump.

Screens out before bed

Switch off about an hour before sleep, and charge phones and tablets outside the bedroom.

Keep the room calm

Cool, dark and quiet helps. Avoid caffeine from mid-afternoon: it is in fizzy drinks, energy drinks, tea, coffee and hot chocolate.

Do it together: Children copy what they see. If the whole family keeps the same wake-up time this weekend, it feels like a routine, not a punishment.

5. If sleep problems carry on

Most children settle back within several days of a steady routine. If your child regularly struggles to fall asleep, wakes a lot, or is very tired in the day despite enough time in bed, talk to your GP.
