Summary. Newborns generally sleep 12 to 16 hours in a 24-hour period and do not know the difference between day and night. Newborns need regular feeding, so they usually sleep in short periods. Newborns sleep in short bursts, known as sleep cycles which are usually around 20 to 50 minutes long.
How Long Will My Newborn Sleep? Newborns should get 14–17 hours of sleep over a 24-hour period, says the National Sleep Foundation. Some newborns may sleep up to 18–19 hours a day. Newborns wake every couple of hours to eat.
In short, newborns sleep so much because they're learning so much and growing so quickly. All that rest helps fuel the big changes they're going through. Newborns sleep up to 17 hours a day. Learn about newborn sleep patterns and how you can establish good sleep habits.
Breastfed newborns' longest sleep periods are generally 2–3 hours — this is about how long their small bellies can go between feedings. If newborns do sleep for a while, they'll probably be extra-hungry during the day and may want to nurse more often.
Once your newborn establishes a pattern of weight gain and reaches the birth-weight milestone, however, it's generally OK to wait for feedings until he or she wakes up. Most newborns need eight to 12 feedings a day — about one feeding every two to three hours.
Young breastfed babies need to feed regularly around the clock. It's not until they're closer to three months of age that many start sleeping for longer periods overnight. However, the general timeframe between overnight feeds is still around 5-6 hours.
The amount of sleep an infant gets at any one stretch of time is mostly ruled by hunger. Newborns will wake up and want to be fed about every three to four hours at first. Do not let your newborn sleep longer than five hours at a time in the first five to six weeks.
Newborns can sleep anywhere from 16-22 hours per day, broken up by feeding, so any sleep within this range should be expected. Your baby may fluctuate on how much sleep she gets, especially if she is experiencing a growth spurt and is feeding more frequently.
For newborns or older babies, you should also call the doctor if the sleepiness coincides with other symptoms, like: Extreme lethargy or listlessness after you wake her, or trouble waking her. Signs of dehydration, like fewer wet diapers, darker colored urine, tearless crying or cracked lips.
Other symptoms: Babies who are extra sleepy, are difficult to wake, or seem too tired to cry, may also show other symptoms of illness. These symptoms could include a fever of over 100.4F (38C), jaundice (a yellow discoloration of their skin), vomiting, or difficulty or disinterest in feeding once a child is awake.
Infants in the first eight weeks have no control over their movements and all their physical activity is involuntary or reflex. They move their bodies while they are awake, but they do not yet know how to make each part of their body move, or even that all the bits belong to them.
All babies are different, but it's very common for babies not to feed all that much in the first 24-48 hours, and some don't attach at all. However, from day 2-3 days babies should become much more awake and feed in more frequent (but probably irregular) bursts at least 6 times in 24 hours.
Lethargic or listless babies appear to have little or no energy. They are drowsy or sluggish. They may also sleep longer than usual. They may be hard to wake for feedings and even when awake, are not alert or attentive to sounds and visual cues.
Generally, newborns sleep a total of about 8 to 9 hours in the daytime and a total of about 8 hours at night. But because they have a small stomach, they must wake every few hours to eat. Most babies don't start sleeping through the night (6 to 8 hours) until at least 3 months of age. But this can vary a lot.
SIDS is most common at 2-4 months of age when the cardiorespiratory system of all infants is in rapid transition and therefore unstable. So, all infants in this age range are at risk for dysfunction of neurological control of breathing.
On the opposite end of the spectrum, some parents may also feel that their babies are not sleeping enough, owing to all the sleepless nights they are subjected to! However, it is completely normal for newborn babies to be sleeping a lot. In fact, on average, newborn babies can sleep up to 18 to 22 hours a day!
As a rule of thumb, a truly hungry baby will rarely choose sleeping over eating. So, if your baby falls asleep in your arms without taking a full feeding, it's likely he was tired — not hungry.
Short nursing sessions are normal – and perfectly fine unless your baby is having trouble gaining weight. Some babies are snackers – they nurse for a minute or two, take a break, and then go back. Other babies can drain the breast in two minutes and be satisfied for a few hours.
Some newborns sleep for up to four hours at a time. Newborns wake frequently to feed because they have tiny tummies. Your newborn might go straight back to sleep after feeding or they might stay awake long enough for a short play. Some newborns get tired after being awake for 1-1½ hours.
Newborns may nurse for up to 20 minutes or longer on one or both breasts. As babies get older and more skilled at breastfeeding, they may take about 5–10 minutes on each side.
Letting your baby sleep for longer periods during the night won't hurt your breastfeeding efforts. Your growing baby can take in more milk during the day — and that, in turn, means longer stretches of sleep at night. Your milk supply will adjust to the new routine.
Exclusively breastfed infants (≤6 months-of-age) had a greater number of night wakings, but most studies (67%) reported no difference in night-time and 24 h sleep duration compared to formula-fed infants.
Your baby is learning to recognize you through their senses. At birth, they are starting to recognize your voices, faces, and smells to figure out who is taking care of them. Since the maternal voice is audible in utero, an infant starts to recognize their mother's voice from the third trimester.
