How much sleep does your baby need?
See typical total sleep ranges by age, with an illustrative split between night sleep and naps. The split is an example, not a recommendation from AASM or NSF.
Every baby is different, so these are typical ranges rather than medical advice. If your baby’s sleep worries you or changes suddenly, talk with your pediatrician.
Total sleep references: AASM recommendations and NSF recommendations. This calculator uses 12–16 hours at 4–5 months and 12–15 at 6–12 months, matching Plumi’s age bands. Night sleep and nap splits are illustrative.
About baby sleep
How much sleep does a baby need?
The National Sleep Foundation gives 14–17 hours for newborns and 12–15 hours for infants. AASM gives 12–16 hours for ages 4–12 months; it does not set a range for babies under 4 months. Both include naps. For ages 1–2 years, AASM gives 11–14 hours. These are general ranges, not a target for an individual baby.
How many naps by age?
Nap counts change with age and vary between babies. Our sample nap generator uses 3 naps at 4–7 months, 2 at 8–13 months and 1 from 14 months. Those counts are model assumptions, not a schedule every baby should follow.
My baby sleeps more or less than this. Is that a problem?
These are ranges, not targets, and healthy babies vary a lot. What matters more is that your baby seems rested and is growing well. If sleep suddenly changes or you’re worried, check with your pediatrician.
Why is my baby’s night sleep broken up?
Night waking to feed is common in early infancy. Longer stretches develop at different times. If waking changes suddenly or concerns you, ask your pediatrician.
How do I know how much my baby actually sleeps?
Plumi’s free sleep tracker records naps and night sleep with timers and daily totals. Plumi Pro adds the 24-hour Rhythm view, so you can compare days.
