Baby Sleep Schedule Planner
Enter your baby's age to see how much sleep to expect, how many naps, and the wake window that helps you time the next one.
Working with your baby's rhythm
Newborn sleep feels random, but there's an age-based pattern underneath it. Knowing roughly how long your baby can stay awake — and how much sleep they need in total — turns nap time from a guessing game into something you can plan the day around.
Line naps up with feeds using the Baby Feeding Amount Calculator, and track how your baby is growing with the Baby Growth Percentile Calculator.
Frequently Asked Questions
What is a wake window?
A wake window is the length of time a baby can comfortably stay awake between sleeps before becoming overtired. Newborns manage only about 45–60 minutes; by a year it stretches to 3–4 hours. Timing the next nap to the end of the age-appropriate window — rather than fighting an overtired baby — is one of the simplest ways to smooth naps and nights.
How much total sleep should a baby get?
Newborns sleep the most — around 14 to 17 hours across the whole day, in short stretches. The total gradually consolidates: roughly 14–16 hours in the first few months, then 12–15 hours by the second half of the first year, with more of it happening at night as the body clock matures.
When do babies drop naps?
Nap numbers fall as wake windows grow. Many newborns take four or more naps; by 4–6 months that often settles to three, then to two around 6–9 months, and to a single nap sometime after the first birthday. Transitions are rarely tidy — expect a week or two of short or rearranged naps each time.
My baby doesn't match these numbers — is that a problem?
Not on its own. These are averages, and healthy babies land all over the range; a baby who's happy, feeding well, and growing is getting the sleep they need even if the totals differ. Use this as a planning guide, not a target. Persistent sleep problems, very short total sleep, or breathing concerns are worth raising with your pediatrician.
Informational averages for planning only, not medical advice. Always follow safe-sleep guidance and speak to your pediatrician about persistent sleep concerns.
