Monthly sleep guide

Baby sleep at 0 months

Here’s what tends to be typical around this age — wake windows between sleeps, the usual number of naps, and total sleep across 24 hours. These are population averages; your baby’s own pattern is what matters most.

Typical wake window1 h – 1 h 30 min

Typical napsVariable
These ranges are general guidance, not medical advice. Every baby is different and wide variation is normal. If you have concerns about your baby’s sleep or health, talk to your pediatrician.

What’s often happening this month

Day and night are still blurred

Newborns don’t yet have a body clock, so sleep is spread fairly evenly across day and night. Light and gentle activity by day, plus calm dark nights, slowly help the rhythm form over the coming weeks.

Short, frequent sleep

At this age sleep comes in short stretches around the clock, often tied to feeds. Very short wake windows are normal — over-tiredness builds quickly, so early, calm wind-downs tend to help.

In the first weeks, sleep comes in short, irregular bursts and wake windows are very short. A predictable rhythm usually appears from around two months.

Common questions

My baby’s sleep doesn’t match these numbers — is something wrong?

Usually not. These are averages, and healthy babies vary a lot from week to week and from one another. A baby who feeds, grows and is generally content is often simply on their own curve. Persistent worries are always worth a chat with your pediatrician.

How much should a baby sleep in 24 hours?

It changes with age and differs between babies. The figure above shows a typical range for this month, day and night combined — treat it as a guide, not a target.

These ranges are population averages, and the variation between healthy babies is wide and completely normal. A monthly guide can calibrate expectations, but it can’t resolve sleep — and no number here should make you anxious. Watch your baby, not only the clock.
