In autumn the clocks go back one hour, which can make a baby wake an hour early by the clock. This year the change falls on Sunday, October 25 in the European Union and the UK, and on Sunday, November 1 in the United States. Most babies adjust within a week or two if you shift the schedule gently.
You have two practical options: change everything at once on the Sunday, or move the schedule in small steps across several days. Both work. Pick the one that suits your family's mornings. For the schedule you are adjusting, see the baby sleep schedule by age and wake windows explained.
What happens to baby sleep when the clocks go back?
Your baby's body clock does not follow the wall clock. When the clocks go back, bedtime, naps and wake-up all seem one hour earlier to your baby. A baby who normally wakes at 6:00 a.m. may wake at what feels like 6:00 a.m. but the clock reads 5:00 a.m. for a short time.
Two ways to shift your baby's schedule
| All at once | Gradual (4 days) | |
|---|---|---|
| How | Use the new clock time from Sunday morning | Move bedtime and naps later by 10 to 15 minutes each day |
| Best for | Babies who adapt quickly, older infants | Sensitive sleepers, babies on a tight schedule |
| Effort | Low; a few tired days | Moderate; takes more planning |
| Risk | Early waking for several days | Longer period of a shifting routine |
all-at-once
Wake your baby at the usual time on the new clock, feed, nap and go to bed by the new clock time, and keep the day consistent. For a few days your baby may seem a little tired or early to wake, which is normal.
gradual
For four days, move bedtime, naps and meals later by 10 to 15 minutes each day. By the fourth day the schedule matches the new clock time.
A day-by-day plan
- Thursday before the change: start moving bedtime and naps 15 minutes later.
- Friday: move another 15 minutes later.
- Saturday: move another 15 minutes later.
- Sunday: use the new clock time for everything; open the curtains in the morning for light.
- Monday to Wednesday: keep meals, naps and bedtime on the new time; offer a short extra nap if your baby is overtired.
How to handle early mornings
- Make the room dark, with blackout curtains, so morning light does not wake your baby. Use a dim night light only.
- Keep waking-up routines calm: do not start the day until the new wake-up time, if your baby is safe and content.
- Use white noise at a safe volume to mask early sounds. See how loud white noise should be.
- If waking comes early for weeks, read why babies wake up at 5 AM.
How a monitor helps during the adjustment
During the adjustment weeks you will wake more often and wonder whether your baby is truly awake. The Baboo baby monitor app lets you check on video and listen in the background without opening the door, and it can alert you to crying or motion. It does not monitor breathing and does not replace adult supervision. For other situations, see baby jet lag and time zone changes.
