Baby sleep schedule by week

Total sleep, naps, and wake windows for every week of the first year — the same data behind every First52 week page.

Sleep needs change fast in year one: from 16–18 hours spread around the clock to 13–14 hours with most of it at night. Ranges below follow the AASM/AAP-endorsed sleep duration consensus for infants and National Sleep Foundation ranges; wake windows reflect common pediatric sleep-practice ranges. Your baby's normal may sit at either edge of a range — the pattern over a week matters more than any single day.
