How to Handle the Clock Change with Your Baby’s Sleep
The Warm and Gentle 2025 Guide for Parents
When it comes to clock change and baby sleep, it can feel daunting – but the good news is that there’s a simple, gentle way to help your baby adjust when the clocks go back by one hour this Sunday (Sunday 26th October 2025).
By using the “split the difference” method for naps and bedtime and keeping wake windows steady, your baby should adjust comfortably within a week.
What is the clock change and how does it affect baby sleep?
When the clocks go back by one hour in autumn, we technically gain an hour of sleep – and mornings become lighter.
But babies don’t follow the clock on the wall; they follow their body clock.
But babies don’t follow the clock on the wall; they follow their body clock.
So, if your baby usually wakes at 7:00 am, the first morning after the change their body may wake them around 6:00 am (new time). Without a plan, the whole day can suddenly feel one hour earlier.
Why the clock change affects babies more than adults
Adults can often power through a mild time shift with a strong coffee and a bit of willpower. Babies, however, rely on predictable rhythms.
Their circadian rhythm is influenced by sleep pressure, light exposure, feeding patterns, and consistent daily routines. A sudden one-hour jump can lead to early morning wakes, overtired evenings, and shorter naps.
Taking a gentle half-step keeps things calm and helps your baby’s body clock catch up – without tears or frustration.
How to prepare for the clock change
You can adjust before or after the change – both approaches work well. Choose the one that best fits your family.
Option A: Prepare in advance (15–30 minute steps)
Three to four days before the change, shift everything later by 15 minutes each day – wake time, naps, meals, and bedtime all move together.
By Sunday, you’ll already be close to the new time, so the switch feels easy and natural.

Option B: Adjust after the change (our favourite)
On Sunday, use the “split the difference” plan below. It’s simple, flexible, and gentle for both babies and parents.
How to handle the day the clocks go back: the gentle “split the difference” plan
This plan is based on what we recommend to families at Baby Sleep The Night. It’s warm, realistic, and easy to follow.
1. Don’t rush to change the clocks first thing.
Get up, open the curtains, have your morning drink, and start the day naturally. Then change the clocks. This helps avoid confusion between “old time” and “new time.”
2. Keep wake windows the same.
Wake windows are about biology, not the wall clock. If your baby usually has a two-hour wake window, stick to that, using the half-step below to gently move naps toward the new schedule.
3. Split the difference for naps.
-
If your baby usually naps at 1:00 pm, put them down at 12:30 pm on Sunday.
-
If the morning nap is usually 9:30 am, make it 9:00 am.
It will feel a little later to their body, helping the transition without the shock of a full hour.
4. Bedtime at 6:30 pm instead of 7:00 pm.
On the first night, aim for 6:30 pm new time. To your baby, it feels like 7:30 pm, but it’s much gentler than jumping straight to 7:00 pm.
5. Repeat for three days.
Use the half-hour shift for around three days. On day four, return to your normal schedule according to the new clock.
6. For babies on wake windows only:
If your baby doesn’t follow set nap times yet, simply nudge the day later by around 10 minutes per day for naps and bedtime. This avoids slipping into a 6–6 routine and helps you get back to a 7–7 rhythm.
Benefits of the gentle approach
-
Kinder for little bodies: halves the strain of a one-hour jump.
-
Protects night sleep: reduces early wakes and bedtime battles.
-
Keeps routines stable: familiar wake windows and feed patterns.
-
Easier for parents: simple steps that work for siblings, too.
Top tips to smooth the transition
-
Light is your friend: get outside in the morning – natural light anchors the body clock. Dim lights in the hour before bed.
-
Protect the first nap: a well-timed first nap keeps the whole day on track.
-
Watch sleepy cues: rubbing eyes, zoning out, or fussing – start the wind down when you see them.
-
Keep bedtime routine the same: bath, PJs, story; familiar steps calm cortisol and help babies settle.
-
Use white noise if it helps: consistent sound can prevent early wakes as mornings brighten.
-
Be flexible with feeds: offer responsive feeds during the transition, then return to usual timing once settled.
-
Hold your nerve: a little protest is normal – consistency is key.
Common mistakes to avoid
-
Pushing the full hour on day one – often leads to overtiredness and early wakes.
-
Dropping naps too soon – keep the safety net while adjusting.
-
Overcorrecting early wakes with an even earlier bedtime – use the half-hour plan instead.
-
Allowing long late naps – cap the last nap to protect bedtime.
-
Inconsistent mornings – start the day at roughly the same time each day.
How long will it take to adjust?
Most babies adjust comfortably within three to seven days using the half-hour plan. Sensitive sleepers may take a little longer.
If your baby already struggles with early mornings or unsettled nights, expect a few bumps – but stay consistent. The gentle approach still works.
FAQs: Clock Change and Baby Sleep
What if my baby wakes at 5 am after the change?
Treat anything before 6 am as night. Keep the room dark and quiet, try a brief resettle, and if you do start the day early, add a little extra nap time and keep bedtime around 6:30 pm for a few days.
