Common questions
How much sleep does a 1 year old need?
12 to 14 hours across a 24-hour period, including one or two naps. Most 1-year-olds still nap twice a day; the morning nap usually drops between 15 and 18 months.
How much sleep does a 2 year old need?
11 to 14 hours total, including one afternoon nap of 1 to 2 hours. Consistent bedtime routines matter more at this age than a precise clock-time.
How much sleep does a 3 year old need?
10 to 13 hours total. Many 3-year-olds are ready to drop the daytime nap; a quiet-time replacement often works better than fighting for a full sleep.
Is this a substitute for a pediatrician?
No. The ranges here are based on published guidance from the American Academy of Pediatrics and the National Sleep Foundation for typically developing children. If your child's sleep pattern looks very different or you have specific concerns, talk to a pediatrician or a certified sleep consultant.
