Sleep hygiene for kids means the daily habits that make good sleep likely: a fixed bedtime and wake time, a calm 30-minute wind-down, a dark cool room, and no screens in the hour before bed. Children who get the hours their age needs learn better, get sick less, and handle their emotions more evenly. Most school-age kids need 9 to 12 hours a night, and most are not getting it.
If bedtime in your house is a nightly negotiation, you are not alone. The fix is rarely one trick. It is a handful of small, boring routines that add up, and the good news is they work at every age.
Key takeaways

- The single most effective habit is the same bedtime and wake time every day, including weekends.
- Screens off one hour before bed, and out of the bedroom overnight.
- Melatonin is not a shortcut. Pediatric melatonin poison control calls rose 530% from 2012 to 2021. Talk to your pediatrician first. [Source: CDC MMWR 2022]
How much sleep does a child need by age?
Children need more sleep than most parents expect, and the target changes with age. The American Academy of Sleep Medicine published the ranges below, and the American Academy of Pediatrics endorsed them. [Source: AAP News 2016]
| Age | Recommended sleep per 24 hours |
|---|---|
| 4 to 12 months | 12 to 16 hours, including naps |
| 1 to 2 years | 11 to 14 hours, including naps |
| 3 to 5 years | 10 to 13 hours, including naps |
| 6 to 12 years | 9 to 12 hours |
| 13 to 18 years | 8 to 10 hours |

Newborns under 4 months are not on the chart because their sleep is not yet organized into a schedule. For that age, safety matters more than hours. Our guide to safe sleep practices for infants covers back-sleeping, the empty crib, and room sharing.
A quick way to check your child: count back from the time they have to be up for school. A 7-year-old who needs to be up at 6:30 needs lights out between 6:30 and 9:30 p.m. Most families land at the late end of that window or past it.
Why does sleep matter so much for children?
Sleep is when the body does its building and the brain does its filing. During deep sleep, growth hormone is released, tissues repair, and the immune system produces the proteins that fight infection. During REM sleep, the brain consolidates what was learned that day.
What that looks like at home is concrete. A well-rested child remembers the spelling list, recovers faster from the cold that went around class, and gets through a disappointing moment without a meltdown. A short-slept child looks wired rather than tired, which is why sleep loss in kids is so often mistaken for a behavior problem. If your child seems to catch everything going around, sleep is worth checking before anything else. Our post on building a strong immune system naturally puts sleep at the top of the list for a reason.

What does a good bedtime routine look like?
A good bedtime routine is the same 3 or 4 calm steps, in the same order, at the same time, every night. It should take 20 to 30 minutes and end in the bed, in the dark, with a parent leaving the room while the child is still awake.
The steps matter less than the consistency. A routine that works for many Sun Pediatrics families:
- Bath or wash up. Warm water followed by a cooler bedroom helps the body’s temperature drop, which is a sleep signal.
- Pajamas and teeth. Same order every night.
- One or two books, in bed. Reading, not a tablet. This is also the best 15 minutes of language development you can buy.
- Lights out, short goodnight, leave. A predictable phrase helps: “Goodnight, I love you, see you in the morning.”
Two habits undo all of the above. The first is a moving bedtime. If lights-out drifts from 7:30 on Monday to 9:00 on Friday to 10:30 on Saturday, the body clock never settles and Sunday night becomes a fight. Hold the schedule within 30 minutes, weekends included. The second is falling asleep somewhere other than the bed, such as the couch or a parent’s arms, and being moved. Children who learn to fall asleep in their own bed also learn to fall back asleep there at 2 a.m. without waking you.
How do screens affect kids’ sleep?
Screens hurt sleep two ways: the light delays the melatonin the brain releases at dusk, and the content keeps the mind alert. The AAP recommends no screens in the hour before bed and no devices in the bedroom overnight. [Source: AAP, HealthyChildren.org]
The bedroom rule is the one parents skip and the one that matters most for teenagers. A phone on the nightstand is a notification at midnight and a scroll at 1 a.m. Charge devices in the kitchen. If your teen argues the phone is their alarm, a five-dollar alarm clock ends the argument. Our guide to how much screen time is too much covers the daytime side.
Should I give my child melatonin?
Not without talking to your pediatrician first. Melatonin is sold as a supplement in the United States, which means the dose on the label is not verified, and gummies look like candy. Between 2012 and 2021, calls to poison control for children who swallowed melatonin rose 530%, and more than 4,000 of those children were hospitalized. [Source: CDC MMWR 2022]
There are children for whom a pediatrician will recommend melatonin, at a specific dose, for a specific period, usually alongside the routine changes above. It is a tool for particular situations, not a nightly fix for a bedtime that keeps drifting. If you are already using it, bring the bottle to your child’s next well-child visit and we will talk it through.
What are the signs my child is not getting enough sleep?
Sleep-deprived children rarely look sleepy. They look wound up. Watch for:
- Hard to wake in the morning, or falling asleep in the car on short drives
- Meltdowns over small things, especially late afternoon
- Trouble focusing at school, or a teacher mentioning restlessness
- Hyperactivity that looks like ADHD, particularly in younger children
- Snoring, mouth breathing, or pauses in breathing during sleep
That last one is different from the others. Loud regular snoring in a child can point to enlarged tonsils or adenoids and disrupted breathing, which no bedtime routine will fix. Mention it at your next visit or book one if it is nightly.
Sleep problems can also show up alongside worry. If bedtime brings tears about school or fears that do not settle with reassurance, our guide to recognizing anxiety in children may help you sort out which came first.
When should I talk to the pediatrician about my child’s sleep?
Bring it up when a sleep problem lasts more than a few weeks despite a consistent routine, when it affects school or mood, or when you see snoring or breathing pauses. Also bring it up if you have started any sleep supplement. Sleep is a standard topic at every well-child visit, and there is no version of the question that is too small.

Frequently asked questions
What time should a 6-year-old go to bed?
Work backward from wake-up time. A 6-year-old needs 9 to 12 hours, so a 6:45 a.m. wake-up means lights out between 6:45 and 9:45 p.m. Most children this age do best around 7:30 to 8:00 p.m. [Source: American Academy of Sleep Medicine]
Is it okay for my child to nap after age 5?
An occasional nap is fine. A daily nap after age 5, or a child who falls asleep at school, usually means night sleep is too short. Move bedtime earlier before cutting the nap.
My teenager cannot fall asleep before midnight. Is that normal?
Partly. The teen body clock shifts later at puberty, so falling asleep at 9 p.m. is hard. But midnight with a 6 a.m. alarm is 6 hours against a need of 8 to 10. Phones out of the bedroom, no caffeine after noon, and a consistent wake time on weekends make the biggest difference. [Source: CDC Youth Risk Behavior Survey 2025]
Does sugar before bed really keep kids awake?
Caffeine does. Sugar’s effect on sleep is less clear than parents assume, but a heavy snack right before bed can cause discomfort. Keep evening snacks small and skip sodas, tea, chocolate, and energy drinks after noon. Our guide to how much sugar is too much for children covers the daytime picture.
