Common questions
What is a wake window?
A wake window is the stretch of time your baby can comfortably stay awake between sleeps. It grows with age — roughly 60 to 90 minutes for a newborn, and several hours by the first birthday — which is why a routine that worked last month often stops working.
How can I tell if my baby is tired?
Early sleepy cues include staring into the distance, going quiet, fussing, yawning, and rubbing at eyes or ears. Catching these early cues — before your baby becomes overtired — usually makes settling much easier.
When do sleep regressions happen?
Regressions are most often reported around 4, 8 and 12 months, when big developmental leaps temporarily disturb sleep. They typically pass within a couple of weeks, once the new skill settles.
What is the best first step if nights are rough?
Start with the day: check that wake windows and nap timing fit your baby's age before changing anything at night. Our free Wake Window Cheat Sheet is the quickest place to start.
