Summer ends the same way every year. Bedtime drifted an hour later in June, another hour in July, and now school starts in a week and your kid is wide awake at midnight. The fix is not complicated, but it works better if you start before the first day rather than after it.
Shift it gradually, not all at once
The method pediatricians recommend is small increments. Begin a week or two before school starts and move bedtime earlier by 15 to 30 minutes a night until you reach the target. Trying to jump from a midnight bedtime to a 9 p.m. bedtime in one night mostly produces a kid lying in the dark, awake and frustrated.
How much sleep you are aiming for depends on age. Preschoolers need up to about 13 hours across the day. Tweens need roughly nine to 12 hours. Teenagers do best with eight to 10.
The hour before bed matters as much as the number on the clock. Skip heavy meals late, and cut screens roughly two hours before sleep. Replace them with something that slows the brain down, a shower, a book, quiet talk. "You're trying to take the cognitive load off your mind," said Dr. Nitun Verma, a spokesperson for the American Academy of Sleep Medicine. "It would be like if you're driving, you're slowly letting go of the gas pedal."
Mornings are the other half, and the underused one. Getting daylight early, sitting by a window or stepping outside, helps train the body clock to wake up. Light is the strongest signal the system responds to, which is why a dark bedroom in the morning makes everything harder.
It also does not have to be rigid. Nikkya Hargrove, a Connecticut author and bookstore owner, moves her twin daughters' bedtimes up 30 minutes the week before school. Sometimes they negotiate for extra reading time, and she lets those conversations happen because her kids are learning to advocate for themselves. When a late night produces a rough morning, that lands as its own lesson. "If they're groggy and they don't like how they feel, then they know, 'OK, I have to go to bed earlier,'" she said.
When the problem is nerves, not habits
Sometimes bedtime is fine and sleep still is not, because a child is lying there worrying about the first day. Duration and quality are different problems.
Pediatrician Dr. Gabrina Dixon of Children's National Hospital suggests asking directly what is worrying them. A new school? Not knowing anyone? Then defuse it with a rehearsal: visit the building, walk the route, go to an open house and meet a few classmates. Turning an unknown into a known does more for sleep than any bedtime adjustment.
"We don't say 'get good sleep' just because," Dixon said. "It really helps kids learn and it helps them function throughout the day." And if the last weeks of summer got away from you and there was no time to prep, she suggests not spiraling about it. "I always say, 'Take a deep breath, it'll be OK.' And just start that schedule." Kids do adjust.
Why teenagers are a harder case
At puberty, the body's internal clock shifts later. Many teens genuinely do not feel sleepy until well after 10 p.m., no matter how disciplined the routine. That is a developmental change, not defiance or laziness. Now put that against a high school that starts at 7:30 a.m. with a bus pickup at 6:45, and the math simply does not allow eight to 10 hours of sleep. A teen doing everything right can still be chronically short.
This is why the American Academy of Pediatrics and sleep medicine groups have recommended that middle and high schools start no earlier than 8:30 a.m., and why the research on later start times is so consistent, a subject we cover in the case against the 8 a.m. start time. The consequences reach further than grades: later starts are linked to measurable safety differences, including in teen car accident rates.
None of that changes your bell schedule this week. But it does change what you should expect from a teenager, and where the pressure belongs. Do what you can at home, protect the morning light and the screen-free wind-down, and recognize that if your district starts high school before 8:30, part of the problem is structural rather than something your kid is doing wrong. Persistent exhaustion also has a way of turning into missed school, which is worth watching for, as we discuss in what actually helps chronically absent students.
