How do I prepare my baby for the spring time change?

Starting 3 to 4 nights before the change, move bedtime, naps, and meals 15 minutes earlier each day. By the time clocks spring forward, your baby is already on the new schedule. Pair this with bright morning light and a dark bedroom.

Do clocks go forward or back for spring forward?

Clocks move forward one hour on the second Sunday in March, so you lose an hour. Bedtime by the clock arrives an hour sooner than your child's body expects, which is why gradually shifting the schedule beforehand helps.

How does light help with the time change?

Bright morning light shifts the internal clock earlier, helping your child feel sleepy at the new bedtime and wake at the new time. In the evening, dim the lights 45 to 60 minutes before bed and use blackout curtains, since spring sunrises come early and can cause early waking.

How long does it take a child to adjust to daylight saving time?

The body typically takes about a week to fully adapt. You can shorten the disruption by shifting the schedule 15 minutes earlier over the few days before the change, getting morning light, and keeping the bedroom dark in the early morning.

Should I wake my baby earlier after springing forward?

Keeping wake time consistent on the new schedule helps the body adjust. Use morning light at the new wake time to reinforce the shift, and keep the room dark before then so early sunrise does not pull wake-up even earlier.

Spring Forward Without Wrecking Your Child's Sleep

When clocks move forward in March, you lose an hour, and bedtime suddenly feels too early to your child's body. Shifting the schedule gradually in the days beforehand softens the change.

The week-before plan

Starting about 3 to 4 nights before the change, move bedtime, naps, and meals 15 minutes earlier each day. By the time clocks spring forward, your child has already adjusted.

A worked example for an 8:00 p.m. bedtime: 7:45, then 7:30, then 7:15 across four nights. After the clocks change, that 7:15 reads as 8:00 again, landing you back on schedule.

Use morning light to reset the clock

On the Sunday of the change, get your child into bright morning light. Morning light shifts the internal clock earlier, helping them feel sleepy at the new bedtime and wake at the new time.

Spending the morning outdoors or by a sunny window is the strongest signal you can give the body to adjust.

Keep evenings and the bedroom dark

Dim household lights in the 45 to 60 minutes before bed to help melatonin release. Lower screens and bright overhead lights as bedtime approaches.

Use blackout or light-blocking curtains in the bedroom. This matters more in spring because the sun rises earlier, and light at 5 or 6 a.m. can trigger early waking.

If you skipped the prep

If you did not shift ahead of time, adjust to the new clock on the day of the change and let your child catch up over several days. The body typically takes about a week to fully adapt.

Keep wake times, naps, and meals consistent on the new schedule, and lean on morning light and a dark room to speed the adjustment.
