How the March 2026 Clock Change Might Affect Your Baby or Toddler’s Sleep

The clocks go forward in the UK on Sunday 29 March 2026, marking the start of British Summer Time.

If you have a baby or toddler, you might be wondering how this time change may affect my child, especially if nights have only just started improving.

The reassuring news is that this clock change comes much easier and most children adjust surprisingly well. In fact, for some families the spring clock change can even help with very early wakeups.

What Happens to Your Child’s Sleep?

When the clocks move forward, we lose an hour overnight.

So, if your child usually goes to bed at 7pm, their body clock will initially feel like it’s 8pm.

Children’s internal body clocks (their circadian rhythm) don’t change instantly. Instead, they gradually adjust based on things like:

• Light exposure

• Mealtimes

• Nap timing

• Bedtime routines

The good news is that most babies and toddlers settle into the new timing within one to two weeks.

Three Simple Ways to Handle the Clock Change

There is no wrong or right way to approach this change, it often depends on your lifestyle and you little one’s temperament. So, it’s ok to choose the option that feels easiest for your family.

Option 1: Do Nothing

For many families, the simplest approach is to carry on as normal.

Many babies and toddlers naturally shift their sleep schedule within a few days without any preparation.

This often works well if your child handles small changes well

Option 2: Shift by 30 Minutes

If you'd like to gently prepare your child, you can split the difference.

On the Saturday night before the clock change:

• Put your child to bed 30 minutes earlier than usual

• Bring naps and mealtimes forward by about 30 minutes

This helps the body clock start adjusting before the clocks change.

Option 3: Adjust Gradually

If your child is very sensitive to routine changes, you might prefer a slow transition.

Starting 4–5 days before the clock change, move daily routines earlier by 10–15 minutes each day, including:

• Wake-up time

• Naps

• Mealtimes

• Bedtime

For example, if bedtime is usually 7:30pm:

• Wednesday: 7:15pm

• Thursday: 7:00pm

• Friday: 6:45pm

• Saturday: 6:30pm

By Sunday evening, your child should already be aligned with the new clock time.

Good News for those families with Early Risers

If your little one regularly wakes around 5am, the spring clock change can actually feel helpful.

That 5am wake-up becomes 6am on the new clock time, which can be a great opportunity to gently reset mornings.

Simple Tips to Help Your Child Adjust

Even with preparation, sleep may feel slightly unsettled for a few days. These small steps can help your child adjust more quickly.

Get outside in the morning
Natural daylight helps reset the body clock.

Keep mealtimes consistent
Regular meal timing supports healthy sleep rhythms.

Keep bedrooms dark at night
Blackout blinds can be very helpful once evenings stay lighter.

Reduce screens before bedtime
Try to avoid screens for at least an hour before sleep.

Stick with your bedtime routine
A calm, predictable routine helps signal that sleep is coming.

If naps are slightly shorter for a few days, try not to worry.

Most children settle into the new rhythm within one to two weeks.

A Gentle Reminder for Tired Parents

If sleep feels a little wobbly during the transition, you’re not doing anything wrong.

Clock changes can be frustrating when you’re already tired, but the disruption is temporary. Your child’s body clock will catch up.

Try to be kind to yourself during the adjustment too.
