Clocks go back an hour this Sunday, November 1, 2026, at 2:00 AM. For most people that’s an extra hour in bed. For parents of a baby, it’s a 5:30 AM wake-up.

Here’s what to expect, and what Ceddie does on the days around the change.

We’re not sleep experts. We’re parents who built an app because we needed one. But this part isn’t in dispute: a baby’s body clock doesn’t move with the wall clock. On Sunday the wake-up, every nap and bedtime land about an hour early on the new clock, and it takes a few days of small nudges before they settle. The spring change is the easy one, because a later wake-up is a gift. The autumn change is the one that costs you sleep.

What Ceddie does

Ceddie knows which time zone your baby is in, so it knows the clocks are about to change. From Thursday, three days before the change, a small calendar clock appears in the top bar and a card shows up on Today:

Clocks go back an hour on Sunday. Ceddie will ease Cedric’s schedule over the next few days.

Tap it and Ceddie explains the change in plain terms: which city, which date, the before and after clocks, and what the schedule is going to do about it. If you’d rather talk it through, the same sheet has an Ask Ceddie about this button that opens the chat with the question already typed: How do I handle the clock change on Sunday?

Then the schedule does the work. On the days around the change, Ceddie moves naps and bedtime 15 to 20 minutes a day over three to four days, so your baby’s body lands on the new clock instead of being dropped onto it. The day’s headline says so, and each nap and bedtime note opens with how far that sleep moved from yesterday, so you always know what you’re looking at:

Nap 2 · 2:35 PM
Wind-down2:20 PM

20 minutes later than yesterday.

Cedric’s wake window stretches a little again today as his schedule moves toward the new clock. Tomorrow's naps move the rest of the way.

Ceddie’s note on the schedule

From Sunday through Wednesday a second card stays on Today:

A few things happen underneath that you shouldn’t have to think about:

  • The night across the change counts as what your baby actually slept. 7:30 PM to 6:45 AM across the autumn change is twelve hours and fifteen minutes, not eleven and a quarter. The wall clock lies that night; Ceddie doesn’t.
  • A time logged inside the repeated hour is read sensibly. Between 1:00 and 2:00 AM on Sunday, every clock time happens twice. If you log a night wake at 1:30, Ceddie takes the one that fits the order of the night.
  • Reminders follow your baby’s clock, so a nap reminder set for 2:35 fires at 2:35 on the new clock.
  • The change day is a normal day. It isn’t hidden from your history and it isn’t used as evidence that your baby is ready to drop a nap.

What to do this week

  • Don’t fight Sunday morning. An early wake the first day or two is expected, and it’s not a sign anything is wrong.
  • Get morning daylight and keep meals on the new clock from Sunday. Light and food are the strongest cues a baby has.
  • Keep the bedtime routine identical. Move the time, not the steps.
  • Log sleeps as you normally would. Ceddie reads the log, not the calendar, and the schedule adjusts from what actually happened.
  • Expect three or four slightly off days, then it’s over.

Sunday is the first clock change since we built this. If something on your Today screen looks off, tap Ask Ceddie or write to us.

Schedules start at three months. If you’re heading into Sunday with a baby and a schedule that’s about to be an hour off, try Ceddie and let it do the arithmetic.
