Newborns typically don't follow a sleep schedule. Their sleep-wake cycles are erratic and unpredictable, with no set nap frequency or duration. Newborns may sleep anywhere from 11 to 19 hours a day in short stretches, and they need to wake up frequently for feedings and comfort. As they grow, their sleep patterns start to consolidate, and they may begin to sleep through the night between 4 and 6 months. By this time, their sleep becomes more predictable, and they can benefit from a flexible routine based on their cues and needs.

What You'll Learn
Newborns sleep a lot, ranging from 11 to 19 hours a day
Newborn sleep is unpredictable, and babies are not born with predictable sleep-wake rhythms. They do not follow a set sleep schedule, nap frequency, or duration. Newborns will wake frequently to eat during the day and at night. Their sleep is driven by sleep pressure (homeostatic sleep drive) and hunger. As they grow and develop, they will be able to stay awake for longer stretches.
It is recommended to wait until a baby is at least 4 to 6 months old before attempting sleep training to encourage a consolidated nighttime sleep schedule. Before this, it is best to base sleep times on sleepy cues and wake windows. A newborn may signal that they are tired through yawning, irritability, and getting a glazed or faraway look.
Around 2 months of age, a newborn's sleep starts to consolidate, and their sleep patterns may become more predictable. Their release of melatonin and cortisol, the hormones that affect sleep and wake cycles, begins to follow a circadian rhythm. This is also when they may start sleeping through the night.

Circadian rhythm takes 3-6 months to develop
Newborns don't follow a sleep schedule. Instead, they sleep in short stretches of 3-4 hours throughout the day and night. This is because they are yet to develop a sense of day and night, and their sleep-wake cycles are not established.
The development of a baby's circadian rhythm, which regulates the timing of bedtime, takes 3-6 months. Circadian rhythm is controlled by an area of the brain that is affected by daylight and darkness, distinguishing between the two to create healthy sleep habits.
During the first few months of life, behavioural observation is often the best measure of sleep. Sleep is entered through active sleep, which usually occurs in about 90-minute stretches for newborns. Newborns can stay awake for short periods, ranging from 30 to 90 minutes, and their sleep patterns can be unpredictable.
As infants reach 8 to 9 weeks old, the release of melatonin and cortisol, the hormones that affect sleep and wake cycles, begins to follow a circadian rhythm. This is when an infant's sleep may start to become more predictable, and their sleep begins to consolidate.
By 4 to 6 months, many babies start sleeping through the night. By this age, it is beneficial to introduce sleep training to establish a proper sleep schedule. This can include routines and sleep cues such as turning down the lights and playing soft music.
While the development of a baby's circadian rhythm typically takes 3-6 months, it is important to remember that every baby is different, and their sleep patterns may vary.

Erratic sleep schedules are normal for newborns
Newborns have erratic sleep schedules, and this is entirely normal. During the first few months of their life, babies do not follow a set sleep schedule. Instead, they sleep in short bursts throughout the day and night. This is because they do not have an established sleep-wake cycle yet.
Sleep Patterns of Newborns
Newborns tend to have unpredictable sleep patterns. They may sleep for 30 minutes during one nap and then 2 hours during the next, and both would be considered normal. At this age, sleep is driven by sleep pressure (homeostatic sleep drive) and hunger, so newborns will wake frequently to eat during the day and night. They may only be able to stay awake for 30-45 minutes before needing to sleep again, although this can vary from 30 minutes to 1.75 hours. Most newborns will sleep a lot, with an average of 16-17 hours of sleep in a 24-hour period. However, this can vary widely and range from 11 to 19 hours of sleep per day.
How to Encourage Healthy Sleep Habits
Since newborns do not have a set sleep schedule, the best way to encourage healthy sleep habits is to respond to their cues and adjust accordingly. Observe your baby's sleep patterns and identify signs of sleepiness before they become too tired. These cues can include yawning, irritability, and a glazed or faraway look. Newborns also need to be fed regularly, so it is important to feed them when they are hungry, whether they are breastfed or bottle-fed.
Around 2 months of age, a newborn's sleep starts to consolidate, and their sleep patterns may become more predictable. This is also when the release of melatonin and cortisol, the hormones that affect sleep, begins to follow a circadian rhythm. However, it is generally recommended to wait until a baby is at least 4 to 6 months old before attempting a strict "by the clock" sleep schedule. Before this, it is best to base sleep times on sleepy cues and wake windows.

Sleep-wake cycles are unpredictable in the first few months
Newborns have varying sleep needs, ranging from 11 to 19 hours of sleep per day. However, they lack a consistent sleep-wake cycle, resulting in unpredictable sleep patterns. This unpredictability can be frustrating for new parents and caregivers, who may worry when their newborn is awake for extended periods at night and sleeps for much of the day.
During the first few months, newborns' sleep-wake cycles are influenced by their developing circadian rhythm and the hormones melatonin and cortisol. As they approach 8 to 9 weeks of age, the release of these hormones starts to follow a more consistent circadian rhythm, leading to more predictable sleep patterns. However, it's important to note that every baby is different, and some parents may not observe a predictable sleep schedule until around 6 months of age.
In the early weeks, newborns may sleep for 30 minutes during one nap and then 2 hours during the next, and both durations are considered normal. Their sleep patterns are driven primarily by sleep pressure and hunger, resulting in frequent waking for feedings and comfort. As a result, newborns may only be able to stay awake for 30 to 45 minutes before needing another nap, and they may sleep for 5 to 6 hours during the day spread over multiple naps.
To manage this unpredictable sleep-wake cycle, parents and caregivers can learn to respond to their baby's sleepy cues and adjust their routines accordingly. Observing signs of sleepiness, such as yawning, irritability, and a glazed look, can help determine when a newborn needs to sleep. Additionally, creating a flexible daytime routine based on the baby's needs and cues can be beneficial, without the pressure of adhering to a rigid schedule.
While newborns' sleep-wake cycles are unpredictable in the first few months, parents can take comfort in knowing that this phase is temporary. By responding to their baby's unique cues and implementing flexible routines, they can promote healthy sleep habits and support their newborn's development.

Sleep training is recommended after 4-6 months
Newborns do not follow a strict sleep schedule. Their sleep patterns are unpredictable, and they tend to sleep during long naps and cannot sleep through the night. Erratic sleep schedules are normal in newborns as they do not have an established sleep-wake cycle.
Sleep training is a popular method to help babies sleep through the night. However, it is recommended to wait until a baby is at least 4 to 6 months old before attempting sleep training. By this age, babies can and should be able to fall asleep or fall back to sleep on their own by self-soothing. Basic self-soothing abilities are still forming at this age, and it is important to remember that self-soothing is not a skill that infants are born with. Their ability to calm themselves down when they are distressed develops gradually over the first two to three years.
There are several sleep training methods that can be used. One method is the fading technique, where parents continue with whatever method they were using to help their baby fall asleep (such as rocking or nursing) but gradually decrease the amount of time spent doing it. Another method is bedtime fading, which involves gradually decreasing the parent's presence in the baby's room when putting them to sleep. This technique can take a long time and requires patience, as parents must wait a few minutes to see if their baby settles down before going in to soothe them.
It is important to note that sleep training may involve some tears, but it is not harmful to babies. It is also important to consider the baby's developmental stage and needs when deciding to sleep train. For example, younger babies may require a parental presence so they do not feel abandoned, especially if they are upset. Additionally, it is recommended to feed a hungry baby, whether they are breastfed or bottle-fed, and to create a comfortable, peaceful, and slightly darker environment before sleep times.
