Wake windows are the amount of time your child is awake between sleeps. When they fit your child's age, falling asleep is easier and nights are calmer.

Start the wake window when your child fully wakes from the last sleep, not when they open their eyes.
Use the shorter end of the range in the morning and the longer end before bed. Most children need the longest awake stretch right before night sleep.
Falling asleep takes 5 to 20 minutes, with mild fussing. The nap lasts at least one full sleep cycle, and your child wakes calmly.
If it takes over 30 minutes to fall asleep or your child is wired at bedtime, the window was likely too long. If they cry hard the moment you offer sleep, it was probably too short.
