Newborn Sleep

How much sleep newborns need and why they wake so often.

Sleep amounts

How much sleep does a newborn need?

Newborns sleep a lot, but not for long stretches. Sleep is spread across the day and night.

16–18 hrs

Weeks 1–2

14–17 hrs

Month 1

13–15 hrs

Months 2–3

Sleep is broken into sessions of 2 to 4 hours. Long stretches at night usually start at 3 to 4 months.

Safe sleep

Three safe sleep rules

These rules reduce the risk of sudden infant death syndrome (SIDS).

😴
Alone

Baby sleeps alone in their own sleep space. No bed-sharing.

⬆️
On their back

Always place baby on their back to sleep, every time.

🛏️
In a crib

Use a firm, flat surface. No pillows, blankets, or bumpers.

Why they wake

Why do newborns wake so often?

A newborn's stomach is very small. It holds about 30 to 60 ml at birth. It empties in 2 to 3 hours, so babies wake to feed.

Newborns also have short sleep cycles of about 45 minutes. They wake briefly between cycles. This is normal.

By 3 to 4 months, many babies start sleeping one longer stretch of 4 to 6 hours at night.

Day and night

Day and night confusion

Many newborns sleep more during the day and wake more at night. This is because they spent nine months in a dark womb where motion during the day was soothing.

To help shift this: keep daytime feeding sessions bright and social. Keep nighttime feeds quiet and dark. This takes 2 to 4 weeks to improve.

Tracking tip

Log night feeds to see your baby's sleep patterns. When you can see the data, it is easier to spot when stretches are getting longer.
