How Much Sleep Does a Baby Need by Age (Chart)

One of the most searched questions from any parent, in any language, is simply: "is my baby sleeping enough?" The short answer is that there are wide reference ranges, not fixed numbers — and individual variability is just as normal as it is among adults. This chart works as a general compass, not a rigid standard to chase every single night.

The reference chart by age

As a general guide for total sleep hours in 24 hours (nighttime plus daytime naps): 0-3 months, 14-17 hours; 4-11 months, 12-15 hours; 1-2 years, 11-14 hours; 3-5 years, 10-13 hours; age 6, roughly 9-11 hours. These ranges are intentionally wide: an 8-month-old sleeping 12 total hours and one sleeping 15 can both be perfectly within normal range.

Reference charts point to a range, not a target to hit every single night.

Average vs exact number: the distinction that matters

A common mistake is treating these numbers as rigid nightly targets, creating unnecessary anxiety when one specific night falls short of the average. The more useful thing to watch isn't the total for a single night, but the trend over one or two weeks, together with the baby's daytime behavior.

A note on methodology: the ranges in this chart summarize the most widely shared general pediatric guidance. Every baby has their own individual rhythm — use these numbers as a reference, not a diagnosis.

Signs your baby is sleeping enough (more reliable than counting hours)

Wakes up relatively content most mornings, without prolonged, inconsolable crying.

Has stable energy and mood during the day, without frequent, marked crashes into fussiness.

Falls asleep within a reasonable window (roughly 10-20 minutes) when put down within their usual routine.

Is growing along their own curve, as tracked by the pediatrician.

What to do if your baby consistently sleeps less than average

If your baby consistently sleeps less than the listed ranges but is content, growing well, and shows no signs of excessive tiredness, they likely just need less sleep than the average — completely normal individual variation. If, on the other hand, there's marked fussiness, growth difficulties, or breathing issues during sleep (frequent snoring, pauses in breathing), it's time to talk to your pediatrician.

The bottom line

Sleep charts are useful as a general compass, not a nightly target to chase. The most reliable signals remain your baby's daytime behavior and growth, not the exact hour count on a tracking app.
