Baby Daily Sleep Calculator

Add nighttime sleep and naps to see the full 24-hour picture rather than judging one nap or one night.

Safe sleep comes first.For every nap and night sleep, follow current pediatric safe-sleep guidance. Place babies on their backs on a firm, flat, level sleep surface with only a fitted sheet. A schedule never overrides feeding, health, or safety needs.

Evidence-backed total sleep ranges

The American Academy of Sleep Medicine recommends 12-16 hours per 24 hours for infants 4-12 months and 11-14 hours for children 1-2 years, including naps. The AASM did not issue a recommendation for babies younger than 4 months because normal sleep varies greatly.

Look at patterns, not one day

Travel, illness, teething, developmental changes, and unusual naps can affect a single day. A multi-day log and your child's mood, feeding, growth, and alertness provide more context.

When the total is outside the range

A calculator cannot determine whether a sleep pattern is healthy. Discuss persistent concerns, difficult breathing, unusual sleepiness, feeding problems, poor growth, or other symptoms with your child's clinician.
