How much sleep does a 3-year-old need?

The National Sleep Foundation range for ages 3–5 is 10–13 hours, which is also where AAP guidance lands after age 2: about 10–12 hours at night plus a nap or quiet time at 36 months.

What wake window does a 3-year-old need?

About 6–6.5 hours from wake-up to nap (or quiet time), and the same from the end of it to bedtime. By 3, the nap often becomes optional — the wake windows still structure the day.

When do most kids stop napping?

Between 3 and 5, with most dropping the daytime nap around 3–4; the AAP keeps quiet time in the day until then. If your 3-year-old still naps well and sleeps at night, there is no reason to stop.

Is there a sleep regression at 3 years old?

There is no classic regression at 36 months — the scheduled disruption is the nap drop itself. Refusal lasting two weeks with easy afternoons marks the transition; hold bedtime steady through it.

36-Month-Old Sleep Schedule

Here is a realistic day for a 36-month-old: wake up around 7:15 AM, one nap or quiet time at 1:00 PM, then bedtime around 8:15 PM. Wake windows run 6 to 6.5 hours, and total sleep lands near 10 to 13 hours. Shift any time 15 to 30 minutes to fit your family, consistency beats the exact minute.

What’s changing at 36 months

Around age 3 many children drop the nap for good — but only when it is truly refused. Dropping early often brings 5 AM wakes and evening meltdowns, so keep quiet time as the stand-in either way.
