Daylight Saving Time and Kids' Sleep: A Pediatrician's Guide to Both Time Changes

Daylight saving time can throw off a child's sleep, but for most kids the change is mild and passes within about a week. The best plan is simple. In the week before the clocks change, gradually shift your child's bedtime, naps, and meals in the opposite direction from the way the clocks move. Many pediatric sleep specialists suggest about 10 to 15 minutes every night or two. Use morning and evening light to help, keep the bedtime routine steady, and expect most children to settle within about a week. You do not have to do the gradual shift if you would rather not. A simple switch works for many families too. This guide covers both the fall "fall back" change and the spring "spring forward" change.

How does daylight saving time affect kids' sleep?

The time change mostly shifts the clock, not your child's body. Kids feel it because their days are tightly scheduled and many are natural early risers.

When the clock changes, your child's internal clock (their "circadian rhythm," the body's built-in 24-hour timer) does not move with it. An adult can adjust by sleeping in or having an extra coffee. A young child cannot. Daycare, naps, meals, and bedtime all stay fixed, so there is no room to absorb a one-hour shift. Young children also tend to wake early by nature, which is why the fall change often brings early morning wake-ups. Babies under about 4 months are the exception. Their internal clock has not fully started yet, so the time change is mostly a non-event for them. The main thing that changes is the feeding schedule written on your clock.

Is it "daylight saving time" or "daylight savings time"?

Both spellings refer to the same thing. The official term is "daylight saving time" (singular), but many parents say "daylight savings time," and either way the effect on your child's sleep is the same.

You will see it written both ways. The technically correct name is daylight saving time, with no "s" on "saving," because it refers to the practice of saving daylight. "Daylight savings time" is so widely used that most people treat the two as interchangeable. Whichever you call it, the plan is the same: shift your child's schedule gradually and keep routines steady.

How long does it take kids to adjust to the time change?

Most children adjust within about a week. Some take a little longer, and steady routines are what move things along.

The American Academy of Pediatrics (AAP) puts it simply.

"While time changes can cause some drowsy days, kids usually adjust within about a week."

American Academy of Pediatrics

You may see a few off days: earlier waking, crankiness, or a harder time falling asleep. That is normal. The best thing you can do is keep every other part of the day steady, including wake time, meals, naps, and the bedtime routine, so your child's body has clear cues to follow. If your child is still struggling after two weeks, that is worth a conversation with your pediatrician.

How to adjust your child's sleep: the gradual method

Start about a week ahead and nudge bedtime, naps, and meals a few minutes each day, in the opposite direction from the way the clocks move.

There are two good ways to handle the change. The gradual method spreads the shift over several days so it barely registers. The AAP advises starting about a week ahead and nudging naps and bedtime a few minutes each day. Pediatric sleep specialists often suggest about 10 to 15 minutes every night or two.

One simple rule covers both time changes. Move your child's schedule in the opposite direction from the way the clocks move.

• Fall back (clocks go back): move bedtime, naps, and meals later in the days beforehand.
• Spring forward (clocks go forward): move bedtime, naps, and meals earlier.

If you would rather not manage a week of small changes, you do not have to. Plenty of families simply change the clocks and let a few days of steady routine do the work. For most kids, that works fine too.

A sample step-by-step shift plan

Pick a day about a week before the change and start here. This example uses 15-minute steps for "fall back," when bedtime moves later.

1. Six to seven nights before: move bedtime, naps, and meals 15 minutes later.
2. Every night or two after that: move another 15 minutes later, until you have covered the full hour.
3. Each morning: open the curtains a little later and keep early light low, so your child does not wake too early.
4. On the day of the change: follow the new clock and keep your normal routine.
5. For "spring forward," do the same steps in reverse, moving everything earlier instead of later.

The "fall back" time change (clocks go back)

In the fall, your child's body still wants to wake at the same moment, but the clock now calls it an hour earlier. Expect early wake-ups, not lost sleep.

Here is the key idea for fall back: nothing changed inside your child. Their body still wants to wake at the same time it always did. That moment is now called 5:00 a.m. instead of 6:00 a.m. Most babies and toddlers come through the fall change with their total sleep essentially unchanged. What changes is the number on the clock. This is actually the healthier of the two changes. The American Academy of Sleep Medicine (AASM) favors permanent standard time because it lines up best with the body's natural rhythm. So think of fall back as a return to better-aligned time that happens to be socially inconvenient for a week, not a health problem.

"Most parents find their young children waking early during fall back to be one of the hardest things to deal with, as it interferes with our own need for sleep in those early morning hours. I definitely recommend a gradual approach to this time change for young children, and room-darkening curtains to help keep out that early morning sun."

Dr. Melissa Tribuzio, MD, Board-Certified Pediatrician

How to stop early-morning waking after fall back

Early waking is the classic fall-back complaint. A few steps help:

• Keep the room dark in the early morning. Blackout curtains can help, so an early dawn does not wake your child.
• Let bright light in later in the morning, and keep the house bright into the evening. This gently nudges the clock later.
• In the week before, push bedtime and naps later so the shift is smaller.
• Watch for the early-evening crash. The AAP notes the fall change can make younger kids crash before bedtime and wake earlier than usual. An overtired meltdown at 5 p.m. can be harder on the family than the early wake-up itself, so protect that late-afternoon nap or quiet time.

The "spring forward" time change (clocks go forward)

In the spring, everyone loses an hour, so this change is a bit harder. Prepare by moving the schedule earlier and getting plenty of morning light.

Spring forward is the tougher change for most people. It is the one linked with more grogginess and disrupted sleep. The good news for parents of little ones: the AAP says the spring change may be a little easier on young children, who tend to be early risers. (Teens often run the opposite way and find spring forward harder.)

To prepare, reverse the fall plan:

• Move bedtime, naps, and meals earlier in the week beforehand.
• Get plenty of bright morning light, and dim the lights after dinner.
• Set the clocks ahead on Saturday evening, keep your child's normal bedtime, and get outside for morning sunlight on Sunday.

Adjusting naps and feeding times

Move naps and meals on the same schedule as bedtime: same amount, same direction, same week.

Naps and meals are part of your child's daily clock, so shift them along with bedtime. Use the same small steps and the same direction. If bedtime moves 15 minutes later for fall back, move naps and meals 15 minutes later too. Meal timing matters more than parents expect, because regular meals are a strong time cue for the body. An earlier dinner can also help, since eating right before bed can cause tummy trouble. Remember that nap hours count toward your child's total daily sleep. For more on how naps change with age, see our guide to baby sleep cycles and milestones.

Age-by-age: babies, toddlers, and school-age kids

Younger babies barely notice the change, while toddlers and school-age kids may need a few steady days. Here is what to expect, and how much total sleep each age needs, including naps.

For newborn sleep basics, see our pediatrician's guide to newborn sleep. For toddlers who wake early or hit a rough patch, our guide to toddler sleep regression can help.

Some kids feel schedule changes more than others. Sleep trouble is very common in children with autism or ADHD, and a shift in the bedtime routine can be especially hard for them. If that sounds like your child, start the gradual shift earlier, closer to two weeks, and keep every other part of the routine exactly the same.

Should you use melatonin for the time change?

Talk to your pediatrician before giving your child melatonin. For a routine time change, light and a steady routine should come first.

Melatonin (the hormone that makes us feel sleepy) is a common question at the time change. Here is the short answer: talk to your pediatrician before giving your child melatonin. It is not the first step for a normal clock change. Healthy sleep habits, morning light, and a steady bedtime routine come first.

A few things every parent should know:

• Melatonin is sold as a supplement, not a regulated medicine, so the amount in a product can vary.
• Doctors know less about long-term use in children, with some concern about effects on growth and development.
• The right choice depends on your child, which is exactly why this is a decision to make with your pediatrician.

When to call your pediatrician

Most kids settle within about a week. If sleep problems last more than two weeks, or you notice snoring or breathing pauses, call your pediatrician.

A few rough nights after the time change are normal. Reach out to your pediatrician if:

• Your child is still struggling to sleep more than two weeks after the change.
• Your child snores most nights (more than three nights a week), or you notice pauses in breathing, gasping, or noisy or labored breathing during sleep.
• Your child breathes through the mouth most of the time, or seems very restless at night.
• Poor sleep is showing up as trouble with attention, learning, or behavior during the day.

"If your child continues to have problems sleeping, talk with your pediatrician."

American Academy of Pediatrics

Your pediatrician will want to know if your child snores most nights, so mention it even if no one asks. These signs are worth checking any time of year, not only at the time change.

How Blueberry Pediatrics can help

The time change can leave you up at odd hours with an early-waking toddler. With Blueberry Pediatrics, you do not have to wait for office hours. Our pediatricians are available by message around the clock, so you can ask about early waking, naps, or whether melatonin makes sense for your child, right when the question comes up. Most kids settle within about a week. If yours does not, we are here to help you figure out why.
