Based on typical ranges published by the Sleep Foundation (medically reviewed by a board-certified pediatrician) and pediatric sleep experts. Note: the American Academy of Sleep Medicine doesn't set official wake-window requirements — use these as starting points and follow your baby's cues.
A wake window is the amount of time your baby can comfortably stay awake between sleep periods — for example, about 2–2.5 hours at 6 months. Tracking wake windows helps you spot when your baby is ready for their next nap or bedtime, instead of guessing.
It gives you a personalized starting point based on your baby's age, morning wake time and naps. Every baby is different, so treat it as a flexible guide and follow your baby's sleep cues.
It changes with age: newborns often take 4–6 naps, babies around 6 months usually take 3, around 12 months usually 2, and by 18 months most are down to 1–2. See the wake-window table above for typical ranges.
Because sleep needs shift from day to day — and as your baby grows. Tracking shows you the pattern, so you can make one small timing tweak instead of overhauling the whole routine.
