School-Age Sleep Needs: How Much Sleep Does Your 5-12 Year Old Need?

Between homework, after-school activities, family time, and the allure of screens, sleep often gets squeezed out of your school-age child's busy schedule. But sleep during these years isn't optional—it's essential for everything from academic performance to emotional regulation to physical growth.

Research consistently shows that well-rested children perform better in school, have fewer behavioral problems, get sick less often, and are happier overall. Understanding exactly how much sleep your 5-12 year old needs—and prioritizing it—is one of the most important things you can do for their success. AAP

How Much Sleep Do School-Age Children Need?

The American Academy of Pediatrics provides clear guidelines: AAP

5-6 year olds:

Recommended: 10-13 hours per night
Most do well with 10-11 hours

7-9 year olds:

Recommended: 9-12 hours per night
Most do well with 10-11 hours

10-12 year olds:

Recommended: 9-12 hours per night
Most do well with 9-10 hours

Important context: These numbers represent the full sleep period, not just time in bed. A child in bed for 10 hours but taking 30 minutes to fall asleep is only sleeping 9.5 hours.

Why Sleep Matters More Than You Think

Sleep during the school-age years directly impacts: NSF

Academic performance:

Memory consolidation happens during sleep
Well-rested children focus better
Problem-solving and creativity improve with adequate sleep
Studies show correlation between sleep and grades

Emotional regulation:

Sleep-deprived children are more irritable, anxious, and impulsive
Difficulty managing frustration
More tantrums and meltdowns
Increased likelihood of conflict with peers

Physical health:

Growth hormone released during deep sleep
Immune function depends on adequate sleep
Obesity risk increases with insufficient sleep
Athletic performance improves with more sleep

Behavior:

Sleep deprivation can look like ADHD symptoms
Better self-control with adequate sleep
Fewer behavior problems at school
More cooperation at home

Sample Sleep Schedules by Age

Kindergarten (age 5-6):
| Time | Activity |
|------|----------|
| 6:30 AM | Wake up |
| 7:00 PM | Start bedtime routine |
| 7:30-8:00 PM | Asleep |
| Total: 10.5-11 hours |

Elementary (ages 7-9):
| Time | Activity |
|------|----------|
| 6:30 AM | Wake up |
| 7:30 PM | Start bedtime routine |
| 8:00-8:30 PM | Asleep |
| Total: 10-10.5 hours |

Upper Elementary (ages 10-12):
| Time | Activity |
|------|----------|
| 6:30 AM | Wake up |
| 8:00 PM | Start bedtime routine |
| 8:30-9:00 PM | Asleep |
| Total: 9.5-10 hours |

Signs Your Child Isn't Getting Enough Sleep

School-age children rarely say "I'm tired"—they show it in other ways: AAP

Academic signs:

Difficulty concentrating in school
Forgetting instructions
Making more mistakes than usual
Grades slipping
Teacher comments about attention

Behavioral signs:

More irritable and moody
Increased tantrums or emotional outbursts
Hyperactive behavior (counterintuitive but common)
Difficulty with transitions
More defiance and arguing

Physical signs:

Difficulty waking up in the morning
Falling asleep during the day or in the car
Dark circles under eyes
Getting sick frequently
Clumsiness, more accidents

Mental health signs:

Increased anxiety
Sadness or depression symptoms
Difficulty coping with stress
Withdrawal from activities

Creating a Healthy Sleep Schedule

1. Work backwards from wake-up time:
If your child needs to wake at 6:30 AM and needs 10 hours of sleep, they should be asleep by 8:30 PM. If bedtime routine takes 30 minutes, start at 8:00 PM.

2. Consistency is crucial:
Same bedtime and wake time every day, including weekends. Sleeping in on weekends disrupts the body clock and makes Monday mornings brutal. Allow only 30-60 minutes variation. NSF

3. Protect the wind-down period:
No homework, no intense activities, no arguments in the hour before bed. Keep it calm: reading, quiet play, family time.

4. Make sleep a priority:
This may mean fewer activities, earlier end to homework time, or saying no to late evening events. Sleep matters more than most other things.

The Screen Problem

Screens are the biggest threat to school-age sleep. Here's what the research shows: AAP

Blue light: Suppresses melatonin, making it harder to fall asleep

Stimulation: Exciting content keeps the brain alert

Displacement: Screen time replaces sleep time

Research findings:

Children with screens in bedrooms sleep less
Screen time before bed delays sleep onset
Social media use correlates with poorer sleep

Recommendations:

No screens for 1 hour before bed (ideally 2)
No devices in the bedroom overnight
Charge all devices outside the bedroom
Use night mode if screens are necessary
Model good screen habits yourself

Common School-Age Sleep Challenges

"But I'm not tired!"
Often they are tired but keyed up. Maintain consistent bedtime anyway. The body clock adjusts over time.

Can't wind down:
Build in a longer transition period. Try: bath, reading together, calm music, deep breathing exercises.

Anxiety at bedtime:
Nighttime often brings worries. Create a "worry time" earlier in the evening. Teach relaxation techniques. Consider keeping a journal.

Early waking:
Ensure room is dark (blackout curtains). Check that bedtime isn't too early. Rule out sleep disorders if it persists.

Resisting bedtime:
Clear expectations, consistent routine, natural consequences (if you delay bedtime, you still wake at the same time).

Helping Your Child Value Sleep

Older school-age children can understand why sleep matters:

Explain the benefits:

"Sleep is when your brain files away everything you learned today"
"Athletes get more sleep before big games because it helps performance"
"When you sleep well, you feel better and have more fun with friends"

Let them experience the difference:

Point out when they feel great after good sleep
Gently note when poor sleep affects their day
Don't use "you're just tired" to dismiss emotions—but help them connect sleep and mood

Involve them in the schedule:

Let them choose elements of the bedtime routine
Discuss what time allows enough sleep
Problem-solve together when things aren't working

What Other Parents Ask

Q: My 8-year-old takes an hour to fall asleep. Is that normal?
A: Most children should fall asleep within 15-30 minutes. If it consistently takes longer, the bedtime might be too early, they might need more physical activity, or there could be underlying anxiety. Try moving bedtime 30 minutes later and see if sleep comes faster. NSF

Q: Should I let my child sleep in on weekends to catch up?
A: Limit sleeping in to 30-60 minutes beyond the usual wake time. Significant weekend sleep-ins disrupt the body clock and make the school week harder. If they desperately need to catch up, an earlier bedtime is better than a late morning. AAP

Q: My child says they can't sleep without the TV on.
A: This is a learned sleep association that can be broken. Transition gradually: TV off but audio on, then quieter audio, then white noise, then nothing. It may take a few weeks but is worth it for better sleep quality.

Q: Is it okay for my 10-year-old to stay up until 10 PM?
A: Probably not if they wake before 7 AM. A 10-year-old needs 9-11 hours. Do the math backwards from wake time. Most 10-year-olds should be asleep by 8:30-9:00 PM for a 6:30 AM wake-up.

The Bottom Line

School-age children need 9-12 hours of sleep per night—more than most are actually getting. Adequate sleep directly impacts academic performance, behavior, emotional regulation, and physical health. Making sleep a priority requires intentional choices about schedules, screens, and activities.

Key points:

5-12 year olds need 9-12 hours of sleep
Work backwards from wake time to set bedtime
Consistency matters—even on weekends
Screens are the biggest threat to adequate sleep
Sleep deprivation can look like behavioral/attention problems
Children can learn to value sleep with the right approach
Sleep matters more than most activities
