How to use a wake window
Count the window from the time your baby woke up. If your baby woke upset, fed poorly, or had a short nap, sleep may need to happen before the larger end of the range.
A wake window supports observation. It should not replace sleep cues, safety, or pediatric guidance.
Signs the window is closing
Early signs are often subtler than crying.
- Staring away.
- Losing interest.
- Yawning.
- Growing fussiness.
- Seeking cuddles or sucking.
Practical adjustments
If your baby takes a long time to fall asleep, the window may be short or the transition may be too stimulating. If your baby arrives crying and wired, it may be too long.
