How 3 month old wake windows change through the day

The first wake window of the day is the shortest. Each one after a nap gets a little longer, with the longest just before bedtime:

WindowLength
First window (after morning wake-up)1 h 15 min
After nap 11 h 25 min
After nap 21 h 40 min
After nap 31 h 50 min
Last window (before bedtime)2 h

What's changing for your 3 month old

  • Many babies roll from tummy to back, so swaddles should be retired.
  • Night sleep may lengthen to a 6–8 hour first stretch.
  • A growth spurt around 3 months can briefly bring back extra feeds.
  • The 4 to 3 nap transition is a few weeks to months away.

What comes next

At 4 months, wake windows grow to 1¾–2½ hours on 3 to 4 naps. Sleep cycles also mature, which is behind the 4-month sleep regression.
