Sleep Hub

Baby Sleep

Newborn to toddler, baby sleep changes faster than almost anything else in the first years. This is your hub for understanding how much sleep your baby needs, how long they can comfortably stay awake, and what to do when a regression turns the whole schedule upside down — all grounded in pediatric sleep science.

The American Academy of Sleep Medicine recommends 12–16 hours of total sleep per 24 hours for infants aged 4 to 12 months, 11–14 hours for toddlers aged 1 to 3 years, and 10–13 hours for preschoolers — naps included. But the headline number only tells part of the story. How that sleep is distributed across naps and nighttime, and how it shifts as your baby grows, is what actually shapes your day.

The guides below break baby sleep into the three questions parents ask most: what a healthy amount of sleep looks like at each age, how to time naps using wake windows, and how to ride out the developmental sleep regressions that disrupt even the best routines.

Schedules by age

Sample clock times, nap counts, and wake windows for every month, from newborn through the toddler years.

Wake windows

How long your baby can comfortably stay awake between sleeps, and how it changes with age.

Sleep regressions

Why sleep suddenly falls apart at predictable ages — and what actually helps.
