Newborns should not go more than about 4–5 hours without feeding. Signs that babies are hungry include: moving their heads from side to side. opening their mouths.
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 typically lose between 5 and 10 percent of their body weight, depending on delivery method, in the days after birth. They need to spend the first few weeks gaining it back. Not eating enough in the first few days can also lead to complications linked to jaundice and low blood sugar.
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.
Between the age of 2 to 3 months old, healthy babies are often able to sleep for six hours without feeding.

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'.
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.
Your brain recognizes hunger as a priority and will stay alert until the need is met, or until you're exhausted enough that the need to sleep overrides the need to eat. So if your baby really is hungry, they usually won't go back to sleep very easily until they've been fed.
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.
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.
Waking up your newborn is common practice for new parents to ensure they're getting enough to eat. It's also advised for breastfeeding mamas so that the baby is at the breast often enough for the body to know to keep producing more milk.
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 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.
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.
Stage 1 Sleeping Through the Night Without Feeding (6 - 8 hours): Around 4 months of age is when most parents will start to see signs from their babies that they're able to sleep in longer stretches. Getting up to 5 and 6 hours by this point is very likely.
Beginning to nurse or feed your baby while they're still calm will facilitate the most successful breastfeeding results. Once crying begins, it can be harder to properly latch.
While there's a lot to learn as a first-time mom, a baby is only considered a newborn for his first 2-3 months of life. Next is the infant stage, which lasts until your baby turns 1 year old.
Your baby may be sleepy the first couple of days after birth and will need to be awakened for feedings. During your hospital stay, expect to nurse your baby every 2-3 hours during the day and at least once or twice during the night. Your baby should not go longer than 4-5 hours without feeding.
"They have enough to survive for the 24 to 48 hours without much in the way of feeding. I am surprised: six days seems a long time to me." After six days the baby was likely to be suffering from low blood sugar and at risk of getting cold. "It's possible, it's surprising.
Bottle-fed babies
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.
In fact, a new baby can be ready for his next nap in as little as 45 minutes. And even at 6 months old, he shouldn't be awake for longer than 2 hours. So yes, your newborn awake for 6 hours straight likely means he's overtired. As always, the best place to start is with your pediatrician.
“For the first two or three weeks after birth, most babies do little but eat and sleep. But they should be waking up for at least 8 to 12 feedings per 24 hours. After three weeks, sleep patterns are more variable, with some babies sleeping longer stretches than others.”
