Baby Sleep Schedule Calculator
Build a rough daily sleep plan for your baby based on age appropriate wake windows, the stretches of awake time babies can usually handle before they need to sleep again. Wake windows lengthen as babies grow, from under an hour for newborns to several hours for toddlers, and stacking a realistic window after each nap helps you predict the next sleepy time and avoid an overtired meltdown. This tool takes your baby age and the morning wake time, then chains typical wake windows and nap lengths for that age to suggest nap start times and a bedtime, along with the total daytime and total daily sleep most babies that age need. Enter the age in months and this morning wake time to see a sample schedule. Every baby is different, so treat this as a flexible starting framework and follow your baby cues. Everything is calculated in your browser, and this is general information, not medical advice.

Frequently asked questions
What are wake windows and how are they set?
A wake window is how long a baby can comfortably stay awake between sleeps, and the tool sizes it by age, from under an hour for newborns up to several hours for older babies.
How does it suggest nap times?
From your baby wake time it chains age-appropriate wake windows and naps, then estimates suggested nap and bedtime slots through the day.
Is total daily sleep the same for every baby?
No; the totals shown are typical ranges by age, and healthy babies vary, so treat the schedule as a flexible guide rather than a fixed rule.
