Question 1

What is a wake window?

Accepted Answer

A wake window is the time a baby is comfortably awake between sleeps—from when they wake to when they go back down. The range grows with age and helps prevent overtiredness.

Question 2

How do I calculate my baby’s wake window?

Accepted Answer

Use the calculator: enter age and the last wake time. It returns a recommended window (min–max) and a suggested nap start. Adjust for your baby’s cues.

Question 3

Are wake windows the same as awake time?

Accepted Answer

Yes—people also say awake window, awake time, wake time, or crib‑to‑crib time.

Question 4

Do wake windows change by age?

Accepted Answer

Yes. Newborns often manage 30–90 minutes, while toddlers can handle several hours. See our age chart.
