The baby clock change happens this year overnight from Saturday 24 to Sunday 25 October 2026: at 3am, the clocks go back to 2am. For a little one, this means waking up, by the clock, an hour earlier than usual. Two approaches work: shift their schedule little by little over the week before, or switch all at once on the Sunday and stay flexible.
Here’s how to choose according to your child’s age, and how to adjust naps, meals, light and bedtime so the transition takes a few days, not a few weeks.
Baby clock change: what actually changes
The switch to winter time is set for the last Sunday in October by European Directive 2000/84/EC. Legal time goes back 60 minutes, but your baby’s internal clock stays exactly where it was.
Take a baby who wakes at 7am and goes to bed at 8pm. From the Sunday, they’ll open their eyes around 6am by the new time. In the evening, they’ll show signs of tiredness around 7pm. Meals, naps and bath time shift in the same way.
For some parents, this shift is rather convenient: an earlier bedtime means a longer evening. For others, a 6am wake-up makes the week harder. So the goal depends on how your household runs.
Why little ones feel the shift
Our sleep-wake rhythm is driven by a biological clock in the brain. According to Inserm (the French National Institute of Health and Medical Research), light is its most powerful synchroniser. Exposure to light late in the day delays the clock; exposure in the morning advances it.
Inserm also notes that some people, children in particular, need several days to get back on track after a time change. A baby doesn’t wear a watch: they follow their tiredness, their hunger and the light. These are the three levers you can work with.
Shift gradually or switch all at once?
No official recommendation settles the question between the two methods. The choice comes down to family habits and your child’s temperament.
The gradual method
This means pushing your baby’s schedule later in small steps over the days beforehand. A step of a quarter of an hour every one or two days is the most common practice. Bedtime, meals and naps all shift by the same amount.
- It suits sensitive children who don’t cope well with a late bedtime.
- It means starting about a week before 25 October.
- It works well alongside evening light, which helps the clock move later.
Switching on the day
You live the Sunday straight on the new time, accepting a few unsettled days. You simply push the first bedtime back by half an hour rather than a full hour.
- It suits adaptable children who adjust quickly to outings and trips.
- It avoids changing a routine that works.
- It means accepting earlier wake-ups for two to five days.
How to go about it according to your baby’s age
Under 3–4 months
In the first months, the day-night rhythm is still developing and feeds set the pace of the day. The clock change matters little at this stage: keep responding to your baby’s needs without trying to shift anything. Simply keep things bright and lively during the day, dark and calm at night.
From 4 months to 1 year
Naps and meals start to settle at fairly regular times. The gradual method is often the most comfortable. Shift bedtime first, then naps, watching for signs of tiredness. Our article on organising naps helps you spot awake windows.
From 1 to 3 years
Days are often structured by nursery or the childminder, who switch to winter time on the Monday. A shift started at home a few days earlier makes the return easier. If you switch over the weekend, the evening routine after nursery acts as an anchor for the first few days.
Naps, meals and bath time: adjusting the rest of the day
Bedtime is only one piece of the puzzle. For the internal clock to follow, the whole day needs to shift in the same direction.
- Meals: shift them at the same time as bedtime, in stages. A baby who gets hungry too early will wake up earlier.
- Naps: avoid a nap that’s too early reinforcing the old rhythm. Push it back by a few minutes each day.
- Bath time: if it’s part of the bedtime routine, it shifts along with it. Our article on evening or morning baths helps you find the right moment.
- The routine: keep the same steps, in the same order. It’s repetition that reassures, not the exact time.
Making light work for you
Since late-day light delays the internal clock, it helps your baby fall asleep and wake up later. An outing in the late afternoon, while it’s still light, pushes things in the right direction.
In the morning, on the other hand, keep the bedroom dim until your desired wake-up time. Blackout curtains limit the effect of the first light. In the evening, choose soft, low lighting during the bedtime routine.
Baby waking too early after the clocks go back: what to do?
This is the most common difficulty with the switch to winter time. A few adjustments help limit it.
- Wait a few minutes before stepping in if they’re babbling calmly.
- Keep the room dark and interaction to a minimum until the target time.
- Push back the first meal a little, without making them wait if they’re crying with hunger.
- Don’t put them to bed later in the evening to compensate: an overtired child often sleeps less well.
- Allow three to five days before deciding the method isn’t working.
Winter time is also heating season
The clock change coincides with the heating going back on. Check the bedroom temperature, which the authorities recommend keeping between 18 and 20 °C for infant sleep. Our guide to the room thermometer explains where to place it.
Beyond the heating, outings, viruses and daylight also change with the season: we’ve gathered the key pointers in our article on your first winter with a baby.
These few days are tiring for parents too. Our tips to recover when nights are short are still useful during the transition.
