How much sleep kids need, by age
These are widely used pediatric sleep ranges (including naps for the youngest):
- 3–5 years: about 10–13 hours
- 6–12 years: about 9–12 hours
- 13–18 years: about 8–10 hours
Every child sits somewhere in their range — some need the top end, some the bottom. Watch how your child wakes and behaves to find their number.
How to find the right bedtime
Work backward, not forward. Start from the fixed point — the time they must be awake — and subtract the sleep their age needs. If your eight-year-old wakes at 6:45 and does best on 11 hours, that's a 7:45 lights-out. Then back up another 30–45 minutes for the wind-down (bath, pajamas, books), and you've got your "start getting ready" time.
Sample bedtimes for a 7:00 wake-up
Aim for the same times on weekends too — a wildly different weekend schedule resets the body clock and makes Monday brutal.
- Preschooler (3–5): asleep by roughly 7:00–8:30 PM.
- School-age (6–12): asleep by roughly 7:30–9:30 PM, depending on their exact need.
Signs your child isn't getting enough sleep
Trouble waking, crankiness or meltdowns late in the day, difficulty focusing, or needing to "catch up" with long weekend lie-ins are all clues the bedtime is too late. Overtired kids often look wired, not sleepy, which fools a lot of parents into pushing bedtime later — usually the opposite of what helps.
Building a bedtime routine that works
Keep it short, predictable, and screen-free in the last hour. A simple sequence — bath, pajamas, teeth, two books, lights out — signals the brain that sleep is coming. The routine matters more than its length; the same calm steps in the same order, every night, do the heavy lifting.
Goodlings can make the wind-down a habit kids own — a gentle bedtime routine they tick off themselves, with a sprout pet that grows for staying consistent.
