Sleep for babies and toddlers
Safe sleep comes first: the AAP says alone, on the back, in a crib. After that, these pages cover how many hours of sleep the American Academy of Sleep Medicine recommends by age, wake windows as typical ranges and not rules, what is known about sleep regressions, bedtime routines, and a planner that runs only in your browser.
