Newborn babies need to feed every few hours until the age of 3 months. After this, it is normal for infants to feed once or twice during the night. Most infants can sleep for 6–8 hours without a feed by the age of 6 months. Once they are 9 months old, most infants can sleep for 11–12 hours without a feed.
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.
Breastfed babies feed often, about every 2–3 hours. Bottle-fed babies tend to feed less often, about every 3–4 hours. Newborns who sleep for longer stretches should be awakened to feed. Wake your baby every 3–4 hours to eat until he or she shows good weight gain, which usually happens within the first couple of weeks.
By 6 months of age, your baby is developmentally ready to start sleeping through the night without a feeding — or at least for longer stretches.
A baby occasionally sleeping for longer than usual is not a cause for concern unless there are other symptoms. In general, it is uncommon for a newborn to consistently sleep through feedings or to sleep for longer than 19 hours per day unless they are ill or are having feeding difficulties.
As a guide, many babies sleep 14-20 hours a day in the first weeks. By 3 months many are settled into a pattern of longer sleep times – perhaps 4 to 5 hours at night. When a baby sleeps about 5 hours straight, this is considered 'sleeping through the night'.
Generally, newborns sleep about 8 to 9 hours in the daytime and about 8 hours at night. But they may not sleep more than 1 to 2 hours at a time. Most babies don't start sleeping through the night (6 to 8 hours) without waking until they are about 3 months old, or until they weigh 12 to 13 pounds.

Until your newborn regains this lost weight — usually within one to two weeks after birth — it's important to feed him or her frequently. This might mean occasionally waking your baby for a feeding, especially if he or she sleeps for a stretch of more than four hours.
A newborn should be put to the breast at least every 2 to 3 hours and nurse for 10 to 15 minutes on each side. But rather than worry about duration, it's important to know that the best way to ensure that the baby is getting enough breast milk is by feeding frequency, wet and dirty diapers, and weight gain.
Your newborn baby's belly is tiny. He or she does not need a lot of milk with each feeding to be full. Your baby may want to eat as often as every 1 to 3 hours. Frequent feeding helps increase your milk supply and gives your baby practice at sucking and swallowing.
Don't worry, baby will ask to be fed as usual as soon as his stomach feels empty again. Your baby may be constipated and appear less hungry than usual, however once this passes everything will go back to normal. Or it may just be that your baby was enjoying the sleep and took longer to wake up.
As newborns get older, they'll nurse less often and have longer stretches between feedings. Newborn babies who are getting formula will likely take about 2–3 ounces every 2–4 hours. Newborns should not go more than about 4–5 hours without feeding.
Your baby's age. Full-term babies who are younger than two weeks should be fed every 3 hours until breastfeeding is established and they've regained their birth weight. A baby under six weeks should not sleep longer than 4-5 hour stretches.
Let them get their sleep so they can continue having enough energy to feed well. Don't push them past their awake window just because you want to show them off. Some babies have easy enough temperaments that they will still be able to get to sleep even though they're getting overtired.
Put baby skin to skin to smell the breast. For the first few days you may need to wake them to feed if they are still sleeping by 3 hours from the last day feeding and 4 hours at night. If baby still won't eat, allow baby to sleep another hour and try again to wake and feed them.
In general, you can expect your baby to sleep an hour per week old they are, starting about 5 weeks old. So, a 5-week-old may be able to go 5 hours, a 6-week-old may be able to go 6 hours, and so on.
The reality is, though, that very few babies sleep through as early as four weeks. Most babies take until six months to sleep through the night. To properly answer your question and address your expectations, we need to defi ne “sleeping through the night”.
While the cause of SIDS is unknown, many clinicians and researchers believe that SIDS is associated with problems in the ability of the baby to arouse from sleep, to detect low levels of oxygen, or a buildup of carbon dioxide in the blood. When babies sleep face down, they may re-breathe exhaled carbon dioxide.
“Babies can still breastfeed on demand—usually they will want to breastfeed every 2-4 hours at this stage,” she notes. “But sometimes they will want to feed every hour and other times will not eat for 5 hours.” All of this is common, she says.
If your baby is older than 6 months, and/or weighs more than 15 pounds, then barring any medical issues, they are absolutely capable of sleeping through the night (11-12 hours) without needing a feed. But this is only true if they are able to take in their entire caloric needs during the daytime hours.
Never force your baby to suck. Always be sensitive to the cues or signals your baby is giving you. Aim for feeding to be a relaxed and calm time. Check the basics, e.g. the flow rate of the teat, the temperature of the milk and the way you're preparing the formula.
Chronic sleepiness, though, can sometimes be a cause for concern. If your newborn is regularly sleeping for more than 17 hours a day and it's interfering with her ability to eat at least eight times per day, you should let your pediatrician know.
Newborn: every 2 to 3 hours. At 2 months: every 3 to 4 hours. At 4 to 6 months: every 4 to 5 hours. At 6+ months: every 4 to 5 hours.
