Daylight saving time and your baby's sleep: how to handle the fall back

On Sunday, November 1, 2026, the clocks go back one hour across most of Canada and the United States. For adults it is a bonus hour of sleep. For a baby with a body clock set to the sun, it usually means waking up an hour earlier by the clock, and a bedtime that suddenly feels an hour too late.

Babies do not read clocks. A baby who wakes at 6:00am today will wake at what the clock calls 5:00am on Sunday. The goal is to move their internal schedule by one hour, and you get to choose how fast.

Option 1: shift gradually the week before

This is the gentlest option, and the best one for babies who are sensitive to schedule changes or who are in the middle of a sleep plan.

• Starting Monday, October 26, move bedtime, naps and meals 10 to 15 minutes later every day or two.
• By Saturday night you are 45 to 60 minutes later than usual.
• On Sunday morning the new clock time lines up with where your baby already is.

It costs a week of slightly later evenings, and on Sunday nothing changes at all.

Option 2: split the difference

For the first three or four days after the change, put your baby down 30 minutes later than their usual bedtime by the new clock. If bedtime is normally 7:00pm, aim for about 7:30pm. Then move to the usual bedtime.

It is a good middle ground when the week before is busy and you cannot plan around it.

Option 3: switch on the day

Some babies, often older ones with steady routines, adjust within two or three days with no preparation at all. On Sunday, simply follow the new clock for naps, meals and bedtime. Expect a few early mornings and slightly short naps while their body catches up.

Which one to pick

• Under 6 months, or mid sleep training: option 1. Small steps protect the progress you have made.
• A baby who is already an early riser: option 1 or 2. Anything that makes mornings earlier will hurt most here.
• An adaptable toddler: option 3 is usually fine.

Stopping the 5am wake up

The fall back is really an early morning problem. A few things help whichever option you choose.

• Keep the room dark in the early morning. After the change, first light arrives an hour earlier by the clock. Blackout blinds or a dark cover over the window stop that light from signalling morning.
• Treat early wakes like night wakes. If your baby wakes before your target wake time, keep it calm, dark and boring until the time you want the day to start.
• Get bright light in the morning. Once the day starts, open the curtains and get outside if you can. Morning light is the strongest signal for resetting a body clock.
• Protect the first nap. An early morning can make the first nap come early too. Stretch the first wake window a little each day rather than letting the whole day slide earlier.

How long it takes

Most babies settle within three days to a week. If you track the next few nights, you will see wake up times drift back toward your target, even when the first morning feels like a step backwards.

Tracking the change in Sleep Sanity

Log the week around the change as usual. The History calendar and the 7 day trend on the Progress screen show whether wake up times are moving back where you want them, so you are not judging the whole plan by one rough Sunday morning.
