Bedtimes drift by two or three hours over a school holiday. That is why the first week back begins with a child who cannot get up and spends the morning in a fog. Here is the order that works for pulling the rhythm back.

1. Know the target first

Sleep guidance puts the daily total at 9 to 12 hours for ages 6–12 and 8 to 10 hours for ages 13–18. If a primary-age child has to be up at seven, that means being asleep between nine and ten. A teenager going past eleven will lose the following morning.

2. Pull the wake-up time, not the bedtime

"From tonight you are going to bed at ten" almost always fails. A child who is not sleepy simply lies there.

Reverse it. Wake earlier and sleep arrives earlier on its own. Move the alarm forward by 15 to 30 minutes a day. Closing a three-hour gap therefore takes roughly two weeks — starting three days before term begins is too late.

3. What morning light actually does

The body clock is set by light. Bright light within 30 minutes of waking starts the day, and sleep pressure builds about fourteen hours later.

Indoor lighting is not enough. Open the curtains, eat breakfast by the window, or step outside briefly. A ten-minute morning walk is the cheapest way to bring bedtime forward.

4. Naps and weekend lie-ins

During the reset, the weekend lie-in is the main obstacle. Two extra hours on Saturday and Sunday puts Monday back where it started. Keep weekends within an hour of the weekday time.

Naps need not be banned outright, but keep them before 3pm and under 30 minutes. Later or longer, and they push the night back.

5. The hour before bed

Screens right up to bedtime do two things at once: the light delays the sleep signal, and the content keeps the brain alert. Games and short-form video are the worst offenders because they have no natural stopping point.

Keeping devices out of the bedroom is the most reliable fix. If that becomes a fight, one household rule — everything charges in the living room — is easier to enforce than a nightly negotiation.

6. Food, caffeine and room temperature

Finish eating two hours before bed. For teenagers, watch caffeine as well: it is in energy drinks and chocolate, not only coffee, and anything after 2pm can show up that night.

Keep the room slightly cool. Core body temperature has to fall for sleep to begin, and a warm room works against it. A lukewarm shower half an hour before bed helps for the same reason.

7. Doing it without a fight

Sleep quickly turns into a battle of wills. The trick is to attach the rule to a clock, not to a person — "the living room lights go off at ten" lands better than "go to sleep". With teenagers, explaining the reason once is worth it: short sleep shortens the process that consolidates what was learned that day, which is an argument that carries weight with someone studying for exams.

8. The two-week plan

Week one — touch only the wake-up time. Move it 15–30 minutes earlier each day and open the curtains immediately. Ignore bedtime for now.

Week two — add the pre-bed hour rule and hold the same times at the weekend. Two days before term, run a full school-day rehearsal.

If after two weeks the child still lies awake for over an hour, is sleepy through the day, or snores heavily with pauses in breathing, this is no longer a habit problem and is worth raising with a doctor. For settling study rhythm once term starts, see thirty minutes a day; on screen limits, see how much screen time.

Sleep duration figures follow paediatric sleep guidance current as of August 2026. Individual needs vary; persistent daytime sleepiness or breathing pauses during sleep should be assessed by a clinician.
