Newborns sleep a lot, but they don't know the difference between day and night. They sleep in short bursts, for around 12 to 18 hours a day. Their sleep patterns can be unpredictable and vary from baby to baby. They also wake up frequently during the night to be fed or changed. However, newborns will gradually learn the difference between night-time and daytime as they grow older. This usually happens around 8 weeks to 3 months of age. There are also some steps you can take to help your newborn establish a healthy sleep pattern.

Newborns sleep in short bursts, known as sleep cycles, which are usually 20-50 minutes long
Newborns sleep in short bursts, known as sleep cycles, which are usually 20 to 50 minutes long. In a 24-hour period, newborns sleep for 12 to 16 hours but do not know the difference between day and night. They do not have established sleep-wake rhythms.
Newborns wake frequently during the night, often because they need to be fed or changed. During the day, they may sleep for longer stretches. This day/night confusion is due to immature circadian sleep-wake systems. It usually improves around 8 weeks, when they may start to learn the rhythm of day and night.
To help your newborn establish a healthy sleep pattern, you can expose them to light and play with them gently during the day. Providing a dim and quiet environment at night can also help signal that it's time for sleep. It's important to create positive sleep associations and a soothing bedtime routine for your newborn. For instance, you could sing a lullaby or use a wind-up musical mobile.
However, some settling techniques may be hard to maintain in the long term. For example, holding your baby until they fall asleep may result in them needing to be held to fall asleep in the future. It's also important to note that feeding routines may impact sleep patterns. If your baby routinely falls asleep while feeding, they may depend on feeding to get to sleep at night. Feeding your baby earlier in the evening can help reduce the frequency of feeding overnight.

Newborns don't know the difference between day and night
Newborns generally sleep 12 to 16 hours in a 24-hour period and do not know the difference between day and night. This is because they do not have established sleep-wake rhythms. They sleep in short bursts, known as sleep cycles, which are usually around 20 to 50 minutes long.
Newborn day and night confusion, also referred to as day and night reversal, occurs when a baby has trouble differentiating between daytime and nighttime hours, and therefore their sleep patterns are irregular. This happens because newborns are adjusting to life outside the dark, noisy womb, and it can take a while for them to settle into their regular sleep patterns. In the womb, babies are lulled to sleep during the day when their mothers are active, and at night, when their mothers are sleeping, they are awake.
To help your newborn establish a healthy sleep pattern, you can engage them in stimulating activities during the day, such as tummy time, gentle play, and interaction with family members. This will help promote alertness and make your baby more tired by nighttime. Exposing them to light and playing with them gently during the day can also help them learn the rhythm of day and night. You can also provide a dim and quiet environment at night to signal that it is time for sleep.
Establishing a calm and relaxing bedtime routine will help your newborn learn the difference between day and night. This routine should be slightly different from what you do to get your baby to nap during the day so that they understand that it is not time for another nap. For example, your bedtime routine could include a bath, dimming the lights, reducing noise, a feed, a massage, a diaper change, and a bedtime song.
Additionally, capping daytime naps to no more than two hours will encourage babies to sleep longer at night. It is also important to ensure that your newborn doesn't nap too much during the day to help with day-night confusion.

Creating positive sleep associations is important
Newborns generally sleep 12 to 16 hours in a 24-hour period, but they do not have established sleep-wake rhythms. They do not know the difference between day and night and often sleep longer stretches during the day, staying awake between sleep cycles at night.
Provide behavioural cues that nighttime is for sleeping and not playtime. Keep the lights dim and maintain a calm environment at night. During the day, open the curtains, play games, and keep things active and busy for your baby.
Expose your baby to light during the day and engage in gentle play to help them learn the difference between day and night. This will help regulate their internal clock and establish normal circadian rhythms.
Create a bedtime routine that is calming and soothing. Reading, singing lullabies, or using a wind-up musical mobile are some activities that can help signal to your baby that it is time for sleep.
Use a baby sling or swaddle to carry and soothe your baby. The Lullaby Trust has information about doing this safely.
Put your baby to bed drowsy but awake. This will help them learn to associate falling asleep with being in bed and will make it easier for them to settle themselves when they wake up at night.
Phase out sleep habits gradually if you need to change them. For example, if your baby falls asleep with music playing, you can turn it off when they start to look drowsy.

A newborn's ability to settle themselves between sleep cycles is called self-settling
Newborns generally sleep 12 to 16 hours in a 24-hour period but do so in short bursts as they do not know the difference between day and night. They do not have established sleep-wake rhythms and their sleep cycles are usually around 20 to 50 minutes long. During active sleep, newborns may move, groan, open their eyes, cry out, or breathe noisily or irregularly. During quiet sleep, they will lie relatively still and their breathing will be more even.
To help your newborn establish healthy sleep patterns, you can follow these simple steps:
- Watch for signs of tiredness and put your baby to bed before they become overtired, as this will make it harder for them to fall asleep.
- During the day, keep your baby active and engaged, and try to keep them awake after they feed.
- Expose your baby to light and play with them gently during the day, and provide a dim and quiet environment at night to help them learn the difference between day and night.
- Put your baby to bed drowsy but awake to help them learn to associate falling asleep with being in bed alone. This can also help with self-soothing, which is when babies can calm down and go back to sleep independently.
- Establish sleep associations, such as a predictable bedtime routine, to help your baby develop positive associations with sleep.

A newborn's sleep patterns can be affected by growth spurts, teething and illnesses
A newborn's sleep patterns can be affected by growth spurts, teething, and illnesses. In the first three months, newborns generally sleep for 12 to 16 hours in a 24-hour period. However, they do not have established sleep-wake rhythms and sleep in short bursts of 20 to 50 minutes. During this time, newborns may experience growth spurts that are linked to increased sleep. In a study, an infant male grew 6.8 cm in 9 saltatory length growth spurts during 93 days, experiencing 10 peaks in total daily sleep hours.
Teething can also impact a newborn's sleep, causing pain and discomfort that make it difficult to sleep. Scientific evidence suggests that more than 80% of infants experience sleep disturbances when teething. Additionally, illnesses can disrupt a newborn's sleep, as they may wake up frequently during the night due to their symptoms.
To help your newborn develop healthy sleep patterns, it is important to create positive sleep associations and a soothing environment. Exposing them to light and gentle play during the day and providing a dim and quiet environment at night can help them learn the difference between day and night. It is also crucial to prioritize their feeding needs and develop a routine together.
While growth spurts, teething, and illnesses can disrupt a newborn's sleep, these are normal parts of their development. By understanding these factors and implementing consistent sleep routines, you can support your newborn in establishing healthy sleep patterns over time.

Frequently asked questions
Newborns generally sleep 12 to 16 hours in a 24-hour period, but only in short periods of 2 to 4 hours.
Newborns have immature circadian sleep-wake systems, so it is common for them to sleep longer during the day and then be awake between sleep cycles at night. You can help them adjust by providing behavioural cues that nighttime isn't playtime and exposing them to light during the day, which will help regulate their internal clock.
Too much stimulation and light exposure at night can signal to their internal clock that it is wake time. It is also important to create positive sleep associations and avoid negative ones, such as holding your baby until they fall asleep, as this can result in them needing to be held to fall asleep.
It can take anywhere from 3 days to 3 weeks to change a baby's sleep habits, depending on the approach and the baby's temperament.
