Newborn Sleep Patterns: Why Are Newborns So Alert?

Newborns generally sleep a lot, with some sleeping up to 19 hours a day. However, newborn sleep patterns vary, and some newborns sleep for shorter periods, with their sleep broken up into 7-8 naps that can last from 15 minutes to 4-6 hours. Newborns also wake frequently to feed, as they have tiny tummies. They don't know the difference between day and night, and their sleep is more likely to be influenced by hunger. So, is it normal for newborns to be awake a lot?

Newborns sleep a lot, typically between 11 and 18 hours in a 24-hour period

Newborns typically sleep between 11 and 18 hours in a 24-hour period. This averages out to around 8–9 hours during the day and 8 hours at night, but this can vary. Some newborns may only sleep for 11 hours per day, while others may sleep for up to 19 hours.

Newborns sleep patterns vary a lot. They don't know the difference between day and night and are often confused, thinking they are supposed to be awake at night and sleep during the day. They also have tiny tummies, so they need to wake up to feed every few hours.

Newborns sleep in short bursts, usually between 2 and 3 hours each, though some newborns sleep for up to 4 hours at a time. They may go straight back to sleep after feeding, or they might stay awake for some playtime.

Newborns have two different kinds of sleep: active sleep and quiet sleep. During active sleep, newborns move around a lot and make noises, and they can be woken easily. During quiet sleep, newborns are still, and their breathing is deep and regular. They are less likely to wake during this type of sleep.

Each newborn sleep cycle includes both active and quiet sleep and takes about 40 minutes. At the end of each cycle, newborns wake up for a little while. They might grizzle or cry, and you might need to help them settle for the next sleep cycle.

In the first few months, newborns usually wake several times a night to feed. Between 1 and 3 months, your baby might start waking less often and having longer periods of sleep at night. By the time they are around 3 months old, they might regularly be having longer sleeps at night, but you can still expect that they will wake at least once.

Newborns sleep in short bursts, usually between 20 and 50 minutes long

Newborns have two different kinds of sleep: active sleep and quiet sleep. During active sleep, newborns move around a lot and make noises. They can be woken easily. During quiet sleep, newborns lie still and their breathing is deep and regular. They are less likely to wake during this type of sleep. Each sleep cycle, which consists of both active and quiet sleep, takes about 40 minutes to complete. At the end of each cycle, newborns will usually wake up for a little while.

Newborns generally sleep for a total of 12 to 18 hours in a 24-hour period. This is usually broken up into 7-8 "naps" that vary in length from 15 minutes to 4-6 hours. Most newborns can stay awake for no longer than 45 minutes to 1 hour and 15 minutes, and some may only manage 30 minutes at a time. As they get older, their window of wakefulness gets longer, and their naps generally become longer and more predictable.

It can be challenging for new parents to know how long and how often a newborn should sleep. There is no set schedule at first, and many newborns confuse day and night. They think they are supposed to be awake at night and sleep during the day. Generally, newborns sleep for about 8 to 9 hours during the day and about 8 hours at night. However, because they have small stomachs, they must wake up every few hours to feed. Most babies don't start sleeping through the night (6 to 8 hours) until at least 3 months of age, but this can vary. Some babies don't sleep through the night until closer to 1 year.

It's important to create positive sleep associations for your newborn and to help them settle when they wake between sleep cycles. You can do this by putting them in their cot when they are tired but still awake, recognising and responding to tired signs, and using a gentle, positive, and consistent routine, such as feed, play, sleep.

Newborns don't know the difference between day and night

Newborns generally sleep for 12 to 17 hours in a 24-hour period. However, they do not have established sleep-wake rhythms and are yet to learn the difference between day and night. This is because the parts of their brains that control day-night sleep cycles have not matured yet.

How to Help Your Newborn Learn the Difference

• Keep them awake a little longer during each waking period during the day. This will help increase their need for sleep later.
• Get your baby outside in the sun. Natural light helps reset their internal clock. If you can’t get outside, place their crib or sleeper near a window that gets steady, bright light.
• Avoid sleep-inducing activities during the day. While you shouldn't fight your baby's need to sleep, keeping them out of the car seat for a bit will help them (and you) later.
• At night, keep the lights low or turned off near the baby's sleeping area. Also, limit sound and movement while your baby is asleep at night.
• Consider swaddling your baby at night. Swaddling can help keep their arms and legs still so they don't move and wake themselves up.

Other Reasons Why Your Newborn is Awake at Night

Hunger

Newborns wake up frequently to feed because they have tiny tummies. They may also wake up thirsty, so a drink of breast milk or formula may do the trick.

Illness

There’s almost always something going on with your newborn’s body, and a lot of it is uncomfortable. They could be teething, have a cold or another illness, or be experiencing gas. Check with your pediatrician if you suspect that pain or illness could be the reason they’re not sleeping.

Overstimulation

Babies are sensitive, and too much stimulation can throw them off their sleeping game. This could be in the form of a nursing parent consuming too much caffeine, receiving too much attention from visitors, or engaging in too much daytime play.

Newborns wake up frequently to feed because they have small stomachs

Newborns have very small stomachs, and their capacity is extremely limited. On the first day, a newborn's stomach is about the size of a cherry and can hold only 5-7 ml (1 teaspoon) at a time. By the third day, the stomach has grown to the size of a walnut and can hold 22-27 ml (4-5 teaspoons). By the end of the first week, the stomach is the size of an apricot and can hold 45-60 ml (1 1/2-2 oz).

Because of their tiny stomachs, newborns need to feed frequently, and this means they wake up a lot. They may go straight back to sleep after feeding or stay awake for some playtime. Newborns need to feed at least 8-12 times in 24 hours, and they usually sleep in short bursts of 2-3 hours at a time.

Newborns also need to feed frequently because their stomachs are slow to expand. On the first and second days, a newborn's stomach does not stretch at all. It is only on the third day that the stomach starts to expand to hold more milk. As the baby's appetite increases, the mother's milk supply increases to keep up with the baby's needs.

Newborns are used to constant nutrition from the placenta before birth. After birth, small, frequent feedings help them transition to an intermittent feeding pattern. To make this transition easier, newborns are provided with small amounts of thick, concentrated milk called colostrum on the first day.

In summary, it is entirely normal for newborns to be awake a lot, and this is primarily because they have tiny stomachs that need to be fed frequently.

Newborns have active and quiet sleep cycles

Newborns have two different kinds of sleep: active sleep and quiet sleep. Active sleep is when newborns move around a lot and make noises. They can be woken easily during this time. Quiet sleep is when newborns are still and their breathing is deep and regular. They are less likely to wake during this time.

Each newborn sleep cycle has both active and quiet sleep, and each cycle takes about 40 minutes. At the end of each cycle, newborns wake up for a little while. They might grizzle or cry, and you might need to help them settle for the next sleep cycle.

During active sleep, newborns may move, groan, open their eyes, cry out, or breathe noisily or irregularly. During the quiet alert phase, newborns are very still but awake and taking in their environment. They may stare at objects and respond to sounds and motion.

Newborns generally sleep for 12 to 18 hours in a 24-hour period. They sleep in short bursts, usually around 20 to 50 minutes long, and wake frequently to feed. They do not know the difference between day and night and do not have established sleep-wake rhythms.

Newborns may sleep more or less than usual when they are sick or when their routine is disrupted. They may also sleep more when they are going through a growth spurt or developmental leap.
