Daylight Saving Time Ended Overnight, and Pediatricians Say Kids Usually Need About a Week Before Their Sleep Settles Back Into Place

The clocks moved back an hour at 2 a.m. today, but children’s internal clocks did not, and in many households a young child was awake and ready for the day while the new clock still said it was early. Dr. Anna Esparham, writing for the American Academy of Pediatrics on HealthyChildren.org, says kids usually adjust within about a week, and that the fall change tends to be harder on younger children, who may fall asleep early and wake earlier than usual.

Clocks fell back on Nov. 1 at 2 a.m. local time, according to Seattle Children’s. Pediatric sleep specialists agree on a short list of habits that help a household through the week, and each one can be started today.

Morning Light Before School

Light is the strongest signal for resetting the body clock. Seattle Children’s recommends outdoor light each morning, even on overcast days, along with some physical activity, and says this matters most on the first day of the change. Dr. Maida Lynn Chen, medical director of the hospital’s Pediatric Sleep Center, said standard time keeps the body clock, the social clock and the solar clock better aligned than daylight saving time does.

Early risers get a different instruction. The American Academy of Sleep Medicine says that in the fall, light exposure should be limited until the target wake time, in its daylight saving time guidance. At Michigan Medicine, pediatric psychologist Dawn Dore-Stites suggests tight window coverings or blackout shades to keep a child asleep until the new morning hour.

Dr. Melissa Eddy-Shelby, a Louisiana pediatrician, makes a similar point about a dark, cool, comfortable bedroom with limited technology, in guidance published by FMOL Health. If a child wakes early and asks for breakfast, she advises making the child wait so the body adjusts to the new time. The pattern is dark until the new wake time, then bright light and fresh air soon after.

Afternoon Play and a Protected Nap

Daytime activity helps sleep, and timing matters. HealthyChildren.org says exercise during the day supports sleep but vigorous activity close to bedtime does not, and that stretching or yoga are better choices later in the day. Dore-Stites advises wrapping up physical play about 90 minutes before bedtime.

For toddlers and preschoolers, naps need a plan. Dore-Stites warned that depriving a child of a nap, or letting a child nap longer during the daylight saving transition, can backfire. She recommends keeping the stretch between waking up and bedtime consistent. Eddy-Shelby likewise advises keeping regular meal, snack and nap times.

Both the AAP and Michigan Medicine describe small moves rather than big ones. Esparham recommends that parents of younger children shift naps and bedtime a few minutes each day in the direction the clocks changed. Dore-Stites said that most children need only a 15 to 30 minute later wake-up on the Sunday of the change, and that children who struggle may need bedtimes, wake times and naps moved 10 to 15 minutes every few days.

An Earlier Dinner

The AAP guidance includes a meal-timing step that many families overlook. Esparham recommends serving dinner earlier, because eating close to bedtime can cause indigestion and make sleep harder.

Seattle Children’s adds a related point about routine. The hospital advises keeping meal times and the bedtime routine on the household’s social clock, so that the family schedule stays consistent from day to day. Put together, the advice is to hold dinner at its regular time by the new clock rather than letting it drift later, and to leave a comfortable gap before bed.

Seattle Children’s also notes that sleep and wake times may shift for a few days, and that sleep can be disrupted at the start and end of the night. An early dinner, a regular bedtime and a predictable morning give the body clock steady anchors while it catches up.

Screens Off an Hour Before Bed

The last step is the one the AAP puts in the plainest terms. Kids should stop using screens at least an hour before bed, because blue light and stimulating content can make them more alert, Esparham writes. She also recommends charging devices outside the bedroom so children are not tempted to check messages or social media at night.

Seattle Children’s likewise calls for less light from screens and media in the evening so that sleep onset is easier. Dore-Stites framed the time change as a chance to end screen habits right before sleep for good.

A steady wind-down routine fills the gap. For younger children, Esparham describes a brush, a book and bed sequence, with cuddling or quiet music. For older children she lists a warm bath, a paper book, soft music or journaling. Dore-Stites adds that praising a child who wakes more easily can help, and that skipping bedtime reading for a night or two is reasonable if a child is overtired.

Teenagers may need extra patience. The AASM recommends eight hours of sleep a night for teens around the time change, and notes that teens are the group at greatest risk because they tend to experience chronic sleep restriction during the school week.

Most families will not need more than these habits. Dore-Stites said even children who have a tough time adjusting usually adapt within a week or two. The AAP advises talking with a pediatrician if problems continue past that point, and Michigan Medicine suggests a sleep clinic if sleepiness or trouble adjusting persists.
