Learn about the typical newborn sleep schedule, including how many hours infants sleep and how their patterns change during the first year.

Understanding the Newborn Sleep Schedule

For the first two months, infants do not have a predictable routine tied to the time of day. Instead, they experience a newborn sleep schedule consisting of short naps lasting one to four hours, spaced throughout a 24-hour period. Because they are born without a strong circadian rhythm—the internal biological clock that manages sleep-wake cycles—they often sleep during the day and stay awake at night.

Daily sleep needs vary significantly. Some infants sleep as little as 11 hours, while others may sleep up to 19 hours every day. These long hours of rest are believed to support the development of the nervous system, brain growth, and the formation of memories and survival instincts.

How Sleep Patterns Evolve

A baby’s sleep-wake cycle develops as they are exposed to light and dark. Around 8 to 9 weeks, hormones like cortisol and melatonin begin to follow a circadian rhythm, making sleep more predictable.

0 to 3 Months: Sleep is erratic and segmented. Wake windows (the time spent awake between naps) typically range from 30 to 90 minutes.
4 to 6 Months: Many infants begin to consolidate their sleep, often achieving at least one uninterrupted five-hour stretch.
9 to 12 Months: Most babies can sleep for eight to nine hours at a time.

Tips for Supporting Newborn Sleep

While you cannot force a baby to sleep through the night, you can encourage healthy habits:

Create a Routine: Use calming activities like rocking, cuddling, or feeding before bed.
Identify Cues: Look for signs of tiredness, such as fussing, crying, rubbing eyes, or staring into space. Place the baby in their crib before they fall completely asleep.
Manage the Environment: Keep the bedroom dark and quiet at night, but provide plenty of sound and light during the day.
Nighttime Feedings: Keep these interactions short and calm with dim lighting.
Tummy Time: Supervised time on their stomach while awake helps muscle development and may be linked to longer nighttime sleep.

Safe Sleep Guidelines

To lower the risk of sudden infant death syndrome (SIDS), follow these safety rules:

Position: Always place the newborn baby on their back to sleep. Avoid placing them on their stomach or side.
Surface: Use a flat, firm surface. The crib or bassinet should contain only a fitted sheet—no pillows, blankets, bumpers, or toys.
Environment: Avoid co-sleeping and do not smoke near the infant.
Pacifiers: Bottle-fed babies can use them from birth. For breastfed infants, it is generally recommended to wait until 3 to 4 weeks old and once breastfeeding is well established. Never tie a pacifier to clothing or the crib.

FAQ

How much do newborns sleep?

Most newborns sleep between 14 and 18 hours daily, though the range can be as wide as 11 to 19 hours.

When will a newborn sleep through the night?

This varies by child. Some begin to sleep longer stretches between 4 and 6 months, while others may not sleep through the night until they are 1 year old.

Can a newborn sleep on their stomach or side?

No. To prevent SIDS, babies should always sleep on their backs. Side sleeping is discouraged because the baby may roll onto their stomach.

When should I wake my newborn to eat?

You should talk to a doctor if your baby does not wake every few hours to feed. Breastfed babies typically eat every two hours, and bottle-fed babies every three to four hours.

When to See a Doctor

Contact a pediatrician if you notice the following:

The baby is unresponsive and cannot be woken up.
The infant is not waking up frequently enough to eat or is not gaining sufficient weight.
You have general concerns about their sleep habits or underlying health issues.
