If your child went to bed at eleven last night and school starts Tuesday, you are not behind. You are normal.
Most back-to-school sleep advice tells you to begin adjusting two or three weeks out. Genuinely useful in mid-August. Not much help on the long weekend before school starts, which is when most of us actually think about it. In BC, that weekend is Labour Day, schools go back the Tuesday, and the gap between good intentions and the first alarm is about seventy-two hours.
So here is the practical version. What to do if you have two weeks, what to do if you have two nights, and how to get through the first rough fortnight without the household coming apart.
Why the Summer Sleep Schedule Is So Hard to Undo
Over the summer, bedtime drifts. Not all at once. Fifteen minutes here, a late movie there, and by the end of August a nine o’clock bedtime has quietly become eleven.
What has shifted is not just a habit. It is your child’s internal clock, which takes its cues from light, activity, and timing, and which resets slowly. That is why telling a child who has been falling asleep at eleven to be asleep by nine tends to produce an hour of ceiling-staring rather than sleep.
The clock has to move. It just will not move on command.
How Much Sleep Kids Actually Need
The Canadian 24-Hour Movement Guidelines recommend:
- Ages 5 to 13: 9 to 11 hours a night
- Ages 14 to 17: 8 to 10 hours a night
Uninterrupted, with consistent bed and wake times. That last part matters more than most families expect, and it is usually the part that slips first.
Work backwards from when your child has to be up. If the alarm goes at 6:45 and your ten-year-old needs ten hours, lights out is 8:45. Seeing the actual number is often the whole intervention.
Start With Wake Time, Not Bedtime
Here is the piece most advice buries, and it is the one that does the work.
You cannot make a child fall asleep. You can absolutely get them up.
Wake time is the stronger anchor. Set it, hold it, and let tiredness do the rest. A child who is woken at seven will be ready for bed earlier that night, and earlier again the night after. A child who sleeps until ten will not be tired at nine no matter how firmly bedtime is announced.
So if you only change one thing, change the morning.
How to Reset When You Have Two Weeks
This is the comfortable version. If you are reading this in mid-August, take it.
The principle is simple. Move both wake time and bedtime 15 to 30 minutes earlier every one to two days, and hold each step until it stops feeling like a fight before you take the next one.
Four things make it work:
- Move the wake time first at each step, then the bedtime. The earlier morning is what makes the earlier night possible, not the other way around.
- Hold a step an extra day if it is not landing. Two weeks has slack built in. A stalled step is not a failed plan.
- Keep weekends on the schedule. Two loose mornings in the middle will undo four days of progress.
- Take the last step before the first day of school, not on it. Arriving already adjusted is the entire point of starting early.
Two weeks is enough to move a schedule by two hours without anyone suffering much. The gradual approach works because it lets the internal clock keep up, which is exactly what a sudden shift does not allow.
How to Reset When You Have Two Days
This is most of us. It is fine. It is just less comfortable.
Do not try to fix bedtime first. It will not work, and you will spend the evening negotiating.
Instead:
- Set the wake time to the school time immediately. Not gradually. Tomorrow. Yes, they will be tired.
- Get them into daylight within half an hour of waking. Breakfast outside, a walk, the back step. Fifteen minutes is enough.
- Keep the day active. A quiet indoor day makes a tired child restless by evening rather than sleepy.
- Move bedtime earlier by half an hour, and accept that is all you get tonight.
- Repeat. By the third or fourth morning, the body catches up on its own.
You are trading one or two rough nights for a schedule that self-corrects inside a week. That is a good trade, and it is a far better outcome than arriving at the first day of school having lost every bedtime argument.
Morning Light Does the Heavy Lifting
Light in the first hour after waking is the single most effective tool you have, and it is free.
Morning light tells the brain to shift the whole cycle earlier, which brings sleepiness forward that evening. It works faster than almost anything else, and it works on adults too, which is worth knowing if your own summer schedule slipped.
Outside beats a window, and a window beats nothing. This matters more here than it does in July, because September mornings on the coast get grey early, and grey mornings send a much weaker signal than a bright one.
Screens, and the Hour Before Bed
The guidelines suggest no more than two hours of recreational screen time a day. Realistic or not in your house, the timing matters more than the total.
The last hour before bed is the one to protect. The usual explanation is blue light, but the bigger problem is simply that screens are engaging. A game or a group chat keeps a brain alert in a way a book does not, and blue light glasses do nothing about that.
Charging phones and tablets outside the bedroom overnight removes the entire negotiation. It is unpopular for about a week, and then it stops being a conversation.
Teenagers Are a Different Problem
If you have a teenager, most of the above still applies. But the reason they cannot sleep is different, and it is worth understanding before the next argument.
Why Your Teen Genuinely Cannot Fall Asleep at Nine
At puberty, two things change at once. The body begins producing melatonin later in the evening, and the pressure to sleep builds more slowly across the day. The Sleep Foundation describes both.
Together they push a teenager’s natural sleep window substantially later. This is a biological change, not a lifestyle choice and not defiance.
In practice, many teenagers are not physically capable of falling asleep before eleven. Sending a fifteen-year-old to bed at nine is asking them to sleep before their body has started producing the hormone that makes sleep possible.
Then the first block starts at around 8:30, and the gap between when they can fall asleep and when they must get up becomes a sleep debt that builds all week.
This is worth saying out loud to your teen. A lot of them have concluded there is something wrong with them.
What Actually Helps a Teen
- Hold the wake time, including weekends. This is the highest-value change by a distance.
- Morning light, immediately. Curtains open, outside if possible. It shifts the clock earlier the way nothing else does.
- Protect the last hour, and phones out of the room. With teens, this works far better as a negotiation than a rule.
- Be realistic about the target. Moving a teen from 1 a.m. to 10:30 p.m. is a win. Expecting nine o’clock is setting up a fight you will lose.
The Weekend Trap
Sleeping until noon on Saturday and Sunday undoes most of the week’s progress.
Two late mornings push the internal clock back again, so Monday feels like jet lag. Researchers call it exactly that. Social jet lag is the term, coined by chronobiologist Till Roenneberg to describe the gap between the clock your body keeps and the one your schedule imposes.
You are not asking for a 7 a.m. Saturday. Capping the weekend sleep-in at an hour or two past the school wake time keeps the clock roughly where you left it, and makes Monday survivable.
Rebuilding the Morning Routine
Sleep is half of it. The other half is that mornings in July have no sequence, and mornings in September need one.
A few things that help:
- Move what you can to the night before. Bags packed, clothes out, lunches made. Morning decisions are the ones that go badly.
- Build the routine as a sequence, not a set of times. Wash, dress, eat, shoes, door. Younger kids follow an order far better than they follow a clock.
- Change one thing at a time. A new bedtime, a new morning routine, and a new after-school schedule in the same week is a lot for anyone.
- Put your own bedtime in the plan. A reset morning routine run by an exhausted parent tends not to survive to Wednesday. September is also when burnout tends to catch up with people, so this is not a small point.
The First Two Weeks Will Be Rough
Expect it, and it will bother you less.
Even with a good reset, the first couple of weeks back usually bring shorter fuses, more tears over small things, and a child who is wiped by four in the afternoon. New teacher, new class, new noise, new everything. Tiredness plus novelty is a lot.
This is not evidence the routine has failed. Most families settle by the end of the second week. Plan a light schedule for those two weeks if you can, and hold the wake time even when the mornings are unpleasant, because consistency is what makes it end sooner.
When Sleep Trouble Is Something Else
Sometimes the problem is not the schedule.
If your child is dreading school rather than just tired, that shows up differently. Stomach aches on Sunday night. Tears at drop-off that do not settle. Questions about whether they have to go. Sleep that will not come because their mind is racing, not because bedtime moved.
That is worth reading about properly, and we have written about it in more depth in Child Anxiety and Separation Anxiety, which covers school refusal, morning drop-offs, and bedtime separation.
It is also worth getting help sooner rather than later. Anxiety about school tends to grow when a child avoids the thing they are afraid of, so the early weeks are a genuinely good time to act.

Frequently Asked Questions
How long does it take to reset a child’s sleep schedule?
Usually about one to two weeks for a shift of an hour or two, moving in 15 to 30 minute steps. A faster reset is possible by holding the new wake time and accepting a few tired days while the body catches up. Younger children tend to adjust more quickly than teenagers, whose internal clocks sit later to begin with.
What time should a 10-year-old go to bed?
Work backwards from the alarm rather than starting from a number. A ten-year-old needs 9 to 11 hours, so with a 6:45 wake time, lights out lands somewhere between 7:45 and 9:45, and around 8:45 is a sensible middle. The better test is how the morning goes. If your child has to be dragged out of bed every day, bedtime is too late, whatever the chart says.
Should I let my child sleep in on weekends?
A little. An hour or two past their school wake time is reasonable and helps with sleep debt. Much beyond that pushes the internal clock later again, so Monday morning feels like jet lag, and you spend the week recovering. Consistency across all seven days is what actually holds a schedule in place.
My child is anxious about school, not just tired. What helps?
Start by separating the two, because they need different responses. A scheduling problem improves once the routine holds. Anxiety usually does not, and it often looks like physical complaints, resistance at drop-off, or a mind that will not settle at bedtime. Our article on child anxiety and separation anxiety goes through the signs and what helps, and if it is not easing after a few weeks, it is worth speaking to a counsellor.
