How much sleep do newborns need daily

The average newborn sleeps much of the day and night, waking only for feedings every few hours. It's often hard for new parents to know how long and how often a newborn should sleep. Unfortunately, there is no set schedule at first, and many newborns have their days and nights confused. They think they are supposed to be awake at night and sleep during the day. Generally, newborns sleep a total of about 8 to 9 hours in the daytime and a total of about 8 hours at night.

Is my newborn sleeping too much?

Yet they awaken frequently, and rarely sleep more than 4 hours at a stretch, even at night. Their internal clocks aren't yet synchronized with the external, hour day. It's a recipe for exhaustion, but understanding the science of sleep can help you cope, and avoid mistakes that can delay your child's development of more mature sleep rhythms. Throughout, I focus on babies under four weeks of age. For information about older infants, see my article on baby sleep patterns.

If you are looking for information about newborn sleep safety, see these science-based tips for reducing the risk of SIDS. To the sleepless parent, newborn sleep might seem totally disorganized.

For example, consider these points. Newborns sleep in short bouts — typically ranging from 30 minutes to 4 hours — at seemingly random times throughout the day and night.

In the first few days, the average newborn sleeps between hours a day Iglowstein et al By four weeks, newborn sleep averages about 14 hours. But the range is considerable. Some four-week-old babies sleep as little as 9 out of 24 hours.

Others sleep for 19 hours a day Iglowstein et al Not necessarily. Some babies suffer from medical conditions that influence the way they sleep, so if you have concerns you should discuss them with your medical provider.

But it appears that many healthy, normal newborns deviate several hours from the average duration of sleep. The timing of adult sleep is governed by circadian rhythms -- physiological changes that follow a hour cycle. Many of these changes are influenced by your exposure to light.

For instance, when you expose yourself to sunlight during the day, you are helping your body calibrate it's internal clock. Even if you are sleep-deprived, morning light helps ensure that you will be more alert during the day than you are at night. Conversely, the absence of light at night helps your body wind down. But as long as you stick with the program -- bright light during the day, and darkness at night -- you will likely find yourself in sync with the natural, hour day.

And of course most adults are in sync. But it's different for newborns. Newborn sleep is not governed by strong circadian rhythms. Things don't begin that way. Not when babies are still in the womb. During pregnancy, fetuses are tuned into their mothers' physiological cues about day and night. Fetal heart and respiratory rates speed up when a mother is active. Such changes may be influenced by maternal hormones, particularly melatonin. Maternal melatonin passes through the placenta, and may direct the fetus' internal clock Torres-Farfan et al But after birth, this intimate hormonal connection is broken.

Newborns must develop their own circadian rhythms of hormone production. As a result, newborn sleep episodes tend to be brief, and spaced at fairly regular intervals around the clock. Most infants take about 12 weeks to show day-night rhythms in the production of melatonin Rivkees Circadian changes in cortisol, a hormone that helps regulate alertness, may take even longer to emerge Rivkees And, overall, babies may take months before they "settle" at night--meaning that they sleep for more than 5 hours at a stretch Jenni et al ; Pinilla and Birch Nevertheless, newborn sleep isn't completely divorced from the natural rhythms of the hour day.

Studies show that circadian rhythms begin developing in the first days after birth. For example, German and Japanese studies have reported that newborns sleep more at night than they do during the day Freudigman and Thoman ; Korte ; Matsuoka et al And scientific evidence suggests that even newborns are receptive to environmental cues about time. You can take advantage of this fact to help shape newborn sleep patterns. When parents include their newborns in their daily activities, newborn may adapt more rapidly to the hour day Custodio et al ; Lorh et al One study took continuous measurements of mother-infant activity patterns for four months after birth.

Newborns who were active at the same time of day as their mothers were quicker to develop mature circadian rhythms Wulff and Siegmund When your baby wakes for night time feedings, keep activity to a minimum. Make as little noise as possible, and avoid moving your baby around. Ideally, you want to avoid waking her "all the way up.

You want the baby to learn that nighttime is for sleep and quiet. For example, in one study, newborns slept longer at night if their parents observed a regular policy of turning out the lights by 9pm Iwata et al In another study, young babies tended to sleep longer at night if they had been exposed to lots of early afternoon light Harrison And time spent outdoors might make an important difference. Babies who go outside experience much higher daytime light levels than those kept indoors all day, and may develop stronger circadian rhythms as a result Tsai et al A recent experiment found that mothers assigned to massage their newborns with lotion at bedtime experienced better newborn sleep outcomes than mothers who massaged without lotion and mothers in a control group who didn't massage at all.

After one month, newborns massaged with lotion were falling asleep faster, staying asleep longer, and awakening at night less often. Mothers using lotion actually massaged their infants more frequently, which may explain the results Field et al An earlier study found that infant massage helped newborns develop more mature patterns of melatonin secretion Ferber The takeaway? More research is needed on this topic Bennett et al , but meanwhile, this seems worth a try.

Do you pump and store breast milk? Consider keeping a record of what time of day you express. Breast milk contains tryptophan, an amino acid that is used by the body to manufacture melatonin.

Tryptophan levels rise and fall according to maternal circadian rhythms, and when infants consume tryptophan before bedtime, they fall asleep faster Steinberg et al It's therefore possible that breastfeeding helps newborn sleep patterns synchronize with the hour day Cubero et al This hypothesis was tested by feeding infants formula fortified with varying concentrations of tryptophan. When infants were given low levels of tryptophan during the day and high concentrations at night mimicking the natural fluctuations of breast milk , infants fell asleep faster at night and got more sleep overall Cubero et al Afterwards, we switch into REM, or "rapid eye movement" sleep, a sleep stage famous for its association with dreaming, and the loss of muscle tone.

We don't move much during REM. When REM is over, we either awaken, or return to light sleep and begin the cycle again. For the average adult, a single sleep cycle lasts about minutes. But we're more likely to wake up "all the way" during transitions between stages, during light sleep, and during REM.

Newborn sleep is also characterized by sleep stages and cycles, but there are crucial differences. Second, newborns in REM don't usually experience muscle atonia. Unlike us, they may thrash around, stretch, twitch, and even vocalize. The results can fool parents into thinking their babies are waking up, when they are actually experiencing normal REM sleep.

It's not unusual for newborns to spend more than half their total sleep time in REM Grigg-Damberger Fourth, while newborns do experience something roughly analogous to deep sleep, this stage, called "quiet sleep," is potentially dangerous. Characterized by slower, more rhythmic breathing, quiet sleep appears more restful Grigg-Damberger But it's harder for babies to awaken from quiet sleep, which can cause trouble if the baby isn't getting enough oxygen.

This may explain why newborns don't oblige exhausted parents by lapsing into long periods of deep sleep. It's too risky. Instead, the typical minute newborn sleep cycle includes only about 20 minutes of quiet sleep.

The rest of the time, babies are either in REM or in "transitional sleep," a rather restless state that looks like a mash-up of active and quiet sleep, and which scientists don't yet understand Grigg-Damberget Put this all together, and you can see why parents feel their babies are such light and erratic sleepers. Like adults, newborns are more likely to awaken during REM, and during transitions between sleep stages.

But unlike adults, newborns spend a lot more time in REM, and they transition between cycles more frequently. And parents may sometimes mistake REM restlessness for waking -- and attempt to interact with or soothe a baby at the wrong time. In short, there are lots of opportunities for babies to wake up -- or get awakened unnecessarily. This sounds like a raw deal for parents. Having a low threshold of arousal may protect babies from SIDS , and active sleep might be crucial for a newborn's brain development Heraghty et al ; Seigel And if we understand the peculiar nature of newborn REM, we can learn to avoid jumping in too soon when we think a baby is awakening or signalling for us.

A baby who seems to be waking up may, if left alone, go back to sleep very rapidly. Don't rush in the moment you think your baby has awakened. As noted above, babies experience frequent arousals, but that doesn't mean they are doomed to wake up "all the way" every few minutes.

Babies often jerk, sigh, or vocalize during partial arousals. If you avoid stimulating them during these moments, they may go back to sleep on their own. Tank up the baby before you go to sleep.

Whether you breastfeed or bottle-fed, try to give the baby an especially large meal before your own bedtime.

How Much Sleep Does Your Baby Really Need?

Just like grown-ups, babies all sleep for different amounts of time. Remember that your baby is unique. He might be doing fine with more or less sleep than other babies the same age.

Yet they awaken frequently, and rarely sleep more than 4 hours at a stretch, even at night. Their internal clocks aren't yet synchronized with the external, hour day.

Newborns sleep an average of 16 or 17 hours a day, with some babies needing a few hours more or less even this young, babies are individuals. However, they may sleep for only one or two hours at a time. During the first three months, your baby will begin to sleep for longer periods at a time, but most infants don't sleep for more than a four-hour stretch, day or night. It's normal for babies to have irregular sleep patterns from birth to 3 months. Newborns haven't yet developed their circadian rhythm. Unpredictable sleep patterns are also due to nutritional needs. Your baby may need to eat every two to three hours in the first month and every three to four hours in the second month.

How Much Should a Newborn Sleep?

Newborn sleeping routines can be puzzling to new parents. As your baby gets used to life outside the womb, they might have trouble adjusting to a daily routine. In the comfort of the womb, your baby spent a lot of time sleeping. They were surrounded by warmth, and lulled by your voice.

Did you know that, according to the National Sleep Foundation , by the age of two, most children will have spent MORE time asleep than awake over the course of their life?

Most newborns spend more time sleeping than they do awake, though the sleep may happen in small chunks or on an irregular schedule. Newly-born babies are not accustomed to schedules or the rhythms of a typical day. For this reason, they might not sleep at the appropriate times. Some people may worry that the baby is sleeping too little or too much.

There's no question about it: Babies and infants need a lot of sleep! How much, exactly? Well, there's no one-size-fits-all answer. Many factors influence how long a baby or infant sleeps, such as whether or not the child is breastfed and how much the baby is exposed to natural light. But these age-related guidelines , below, can help you figure out what's best for your bundle of joy. Full-term, healthy newborns or infants up to about three months old should spend the better part of a hour day sleeping.
