Naps & bedtime

How long your baby can comfortably stay awake, and what that makes of today. Overtired babies fight sleep hardest, so the wake window is usually the thing to fix first.

How old is your baby?

Awake between sleeps

2 hr – 2 hr 45 min

Naps a day

2–3

Sleep in 24 hours

12–16 hours

6-8 months. Most babies settle into three naps here, then drop to two towards the end of it.
