Baby Sleep Schedule by Age 0 - 12 Months | Baby Sleep Patterns

Understanding your baby's sleep schedule can make a huge difference for both parents and babies. During the first 12 months, sleep patterns change quickly as your baby grows and develops.

Many parents worry about whether their baby is getting enough sleep, sleeping the right number of hours at night, or following a normal routine. The truth is that every baby is different, and sleep schedules are simply helpful guides rather than strict rules.

As babies grow, their sleep cycle, wake windows, and nap needs change. Learning about baby sleep patterns by age can help parents understand when babies need sleep, how long they may stay awake, and how to support better rest.

On Parenting Hub, parents can also explore helpful sleep tools such as the Baby Sleep Planner, Wake Window Calculator, and Baby Nap Calculator to better understand their baby’s sleep needs.

 

Newborn Sleep Schedule (0–2 Months)

During the newborn stage, sleep patterns are unpredictable. Newborn babies often sleep 14–17 hours a day, but this sleep happens in short blocks spread throughout the day and night.

Because newborns need frequent feeding, their sleep is closely connected to feeding routines. Babies may wake every two to three hours for feeding, which means night sleep is often interrupted.

Common newborn sleep characteristics include:

• Frequent feeding
• Short wake windows
• Irregular daytime sleep
• Many short naps
• Active sleep phases

Newborns have shorter sleep cycles, which means they move between active sleep and deep sleep more often than older babies.

Parents should focus on responding to their baby’s needs rather than enforcing a strict schedule during this stage.

Helpful tool:
Use the Baby Sleep Planner to track your newborn’s sleep and feeding patterns.

 

3 Month Baby Sleep Schedule

By around 3 months, many babies begin developing slightly more predictable sleep patterns.

Wake windows lengthen, usually to 1–2 hours, and babies may start forming early nap patterns during the day.

At this stage, parents often notice:

• Longer wake windows
• Emerging nap patterns
• Bedtime routines beginning
• Slightly longer stretches of sleep through the night

Babies may still wake for night feeds, but some begin sleeping for longer periods.

Creating a simple bedtime routine can help babies recognise sleep cues and settle more easily.

Helpful tool:
Try the Wake Window Calculator to determine the ideal wake window for your baby’s age.

 

4 Month Sleep Regression - Baby Sleep Schedule by Age

Around 4 months, many babies experience a temporary change in sleep known as the 4 month sleep regression.

This happens because babies’ sleep cycles mature, becoming more similar to adult sleep patterns. As a result, babies may wake more frequently during the night.

Common signs include:

• Changes in sleep patterns
• Developmental growth
• Increased sleep disruptions
• Shorter naps

Although challenging, this phase is a normal part of development and usually improves with time.

Helpful tool:
Use the Sleep Regression Calculator to identify whether your baby may be experiencing a sleep regression.

 

6 Month Sleep - Baby Sleep Schedule by Age

By around 6 months old, many babies begin following a more predictable routine.

Wake windows typically last 2–3 hours, and babies may settle into 2 or 3 naps per day.

Typical changes include:

• More predictable naps
• Longer stretches of sleep at night
• A clearer daily sleep routine

At this stage, babies often benefit from a consistent bedtime routine, which may include feeding, quiet play, and calming activities before sleep.

Parents often find that babies start sleeping longer overnight while maintaining regular daytime naps.

Helpful tool:
Use the Baby Nap Calculator to help plan your baby’s nap schedule.

 

9 Month Sleep Schedule

Around 9 months, babies may go through another developmental phase that affects sleep.

Some babies experience separation anxiety, which can make bedtime more challenging.

Sleep changes may include:

• Separation anxiety
• Nap transitions
• Changes in baby sleep patterns
• Temporary sleep disruptions

Despite these changes, most babies still need about 12–14 hours of total sleep each day.

Parents can help by maintaining consistent routines and recognising signs that their baby may be overtired.

Helpful tool:
Use the Overtired Baby Signs Checker to recognise when your baby may need sleep.

 

12 Month Sleep Schedule

By 12 months, many babies transition toward a toddler sleep routine.

Most babies take one or two naps during the day and sleep longer overnight.

Typical sleep includes:

• Nap transitions
• More structured bedtime routines
• About 12–14 hours of sleep per day

Some babies begin dropping a second nap around this time, although every baby develops differently.

Parents can support healthy sleep habits by maintaining consistent bedtimes and recognising when their baby is ready for sleep.

Helpful tool:
Track your baby's sleep using the Baby Sleep Schedule Tracker. Helping the baby to sleep.

If your baby wakes during the night, gentle soothing can help them go back to sleep, making it easier to settle them again. 

Baby Sleep Chart by Age

Sleep charts can help parents quickly understand how babies' sleep patterns change as they grow.

Age	Wake Window	Naps	Total Sleep
Newborn	45–60 min	4–6	14–17 hrs
3 months	1–2 hrs	3–4	14–16 hrs
6 months	2–3 hrs	2–3	13–15 hrs
9 months	3–4 hrs	2	12–14 hrs
12 months	3–4 hrs	1–2	12–14 hrs

These ranges are general guidelines. Every baby grows at their own pace, and sleep needs can vary.

Final Thoughts – Baby Sleep Schedule by Age

Understanding an infant's sleep by age can help parents feel more confident about their baby’s sleep needs during the first year.

While sleep habits change frequently during the first year, recognising wake windows, nap patterns, and sleep cues can help parents support better sleep time for their baby.

Remember that every baby or toddler is different, and flexibility is important when establishing routines.
