The clock change and your child's sleep

Twice a year, the clocks go forward or back, and our children do not read the time. On the evening of the change, bedtime can feel off: too early for them, or on the contrary far too late. No need for a complicated method. By shifting bedtime gently, in small steps, and keeping the same evening routine, you help your child find their rhythm again without a jolt.

Why does the clock change unsettle bedtime?

Because children run on habits, not on the clock. Evening after evening, they have learned when the bath comes, then the story, the cuddle, and sleep. When the time on the clock jumps all at once, their habits have not moved. The result: one evening you ask them to go to bed when they do not feel ready; another, they are falling asleep long before the usual time. This small gap explains the slightly topsy-turvy evenings of the days that follow.

Nothing to worry about: it is a matter of adjusting, and it happens. Naître et grandir, a parenting reference site from Québec, puts it simply: “You can reduce the impact of the time change on your child by changing their bedtime little by little.” Everything is in that “little by little”. No upheaval, just a nudge so that their routine catches up with the new time.

Shifting bedtime gently, in small steps

The simplest approach is not to change everything on the same evening. Rather than jumping straight to the new time, you slide bedtime by a few minutes at a time, over several days, until you land on the time you want. Your child follows along without even noticing, because the shift stays tiny from one evening to the next.

In practice, here is a gentle way to handle the clock change:

1. If you can, start the week before, shifting bedtime by a few minutes each evening, in the direction of the change.
2. Shift the landmarks of the day as well, in the same direction and at the same pace: meals, and the nap if there still is one.
3. Go step by step, without trying to catch up in a single night. Progress matters more than speed.
4. Keep exactly the same evening routine: same gestures, same order, only the time moves slightly.
5. During the day, let them play outside in daylight: it helps their internal clock settle onto the new time.

If you did not plan ahead, that is fine. You can also make this gradual shift in the days after the change, until everyone is back on their usual schedule. The key is to go gently, without pressure.

In autumn, when the clocks go back, some children start waking up earlier in the morning. Naître et grandir then advises you to “protect your child's sleep in the morning”: no loud noises, and curtains drawn tight to block the morning light.

The evening routine, your best landmark

When the time gets muddled, the routine puts things back in order. Your child may not know it is “an hour earlier”, but they know the story comes after the pyjamas, and sleep comes after the story. This familiar sequence tells them the day is ending, whatever the clock says. Naître et grandir points out that a good bedtime routine “helps your child gradually calm their body and mind”.

So take extra care of the last hour before bed during this period. Naître et grandir advises that “the hour before bedtime should be calm”: quiet games, dimmed light, a soft voice. It is even more useful on evenings when the rhythm is a little off, because a calm child falls asleep more easily, even if the time is not quite what it used to be. And keeping regular hours once the change has passed helps everything settle: France's national health insurance, the Assurance Maladie, recommends “regular bedtimes and wake-up times, even at weekends”.

How long does it take to get back on track?

A few days, sometimes a little longer, and every child has their own pace. For the spring change, Naître et grandir notes that children generally get used to the new time “in about a week, but some need more time”. What matters is not to make a drama out of a late bedtime or a slightly early wake-up during those few days. By keeping the routine steady and shifting the times gently, the rhythm comes back.

During this little interlude, a bit of flexibility does everyone good, parents included. Is your child grumpier, waking up a bit more? Naître et grandir reminds parents: “If your child is more difficult than usual, remember that it is temporary.” Stay consistent with the evening gestures and patient with the rest. If unusual tiredness or sleep difficulties carry on well beyond, talk to your doctor.
