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.
Do not let your newborn sleep longer than five hours at a time in the first five to six weeks. Thereafter, you can keep the following general milestones in mind: By four months, most babies begin to show some preferences for longer sleep at night.
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.
If all of those factors are lined up though, it is entirely possible for a baby as young as 6 weeks old to sleep for a solid 6-8 hours, or even longer, overnight. It can, and does, happen!
Newborns generally sleep for two to three hours before waking to eat, day and night. As they get older, babies are usually able to sleep for increasingly longer stretches of time at night without waking to eat. Between the age of 2 to 3 months old, healthy babies are often able to sleep for six hours without feeding.

7-Week-Old Baby Sleep
Your 7-week-old baby should be sleeping really well (in SNOO babies often have 5, 6, or even 7-hour stretches of continuous sleep). And all that rest is helping them make the most of their awake periods.
Between weeks seven and ten, most Babywise babies drop their middle-of-the-night feeding and begin sleeping 8 hours at night. Eight cycles are now reduced to seven. Your baby, however, will not be reducing his daily caloric intake, just rearranging when he takes those calories.
Your 7-week-old baby's development
Newborns up to 3 or 4 months old need 14 to 17 hours of sleep in a 24-hour period, usually waking every two to four hours to eat. Breastfed babies should eat as much as they want at this age, but a general rule of thumb is roughly 24 to 32 ounces of breast milk or formula in 24 hours.
Once your child is about 6 or 8 weeks old, he or she should start to sleep for longer periods at night and shorter periods during the day. By the time your baby is 8 weeks old, night sleep may last six hours or more, and by the time he or she is a few months old, sleeping through the night is possible.
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.
Here's how often you can expect your baby to eat at night during the 0 - 2 month age timeframe: Breastfed Babies - 3 to 5 feedings per night. Formula-fed Babies - 2 to 4 feedings per night.
Newborns usually sleep in short bursts of 2-3 hours each. 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.
Most also wake up at least every 3 hours to feed. However, this timing varies widely. Some newborns may only sleep for 11 hours per day, while others may sleep for up to 19 hours per day. Also, newborns may sleep more or less than usual when they are sick or when they experience a disruption to their regular routine.
There isn't a universal answer to this. Some newborns do best with a 7:00-8:00 pm bedtime. These newborns, when kept up past 8:00 pm, start to become fussy and overtired. On the other hand, some babies thrive with a nap around 7:00 pm and bedtime between 8:00 and 10:00 pm.
First Weeks and Months
On average, most exclusively breastfed babies will feed about every 2 to 4 hours. Some babies may feed as often as every hour at times, often called cluster feeding. Or may have a longer sleep interval of 4 to 5 hours. How often your baby feeds might change depending on the time of day.
How Long Can My Baby Go Without a Feed? Newborns can generally go about two and a half hours between feeds. This time slowly extends until about six months when babies can go about four hours between daytime feeds and sleep all night without a feed. But, some smaller babies may need an extra night feed for longer.
Being overtired is the most likely reason why your newborn is awake instead of napping, as newborns have VERY short wake windows and can become overtired very easily. Once a newborn becomes overtired, it becomes extremely difficult to get them to sleep.
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.
Growth spurts happen at fairly regular intervals in the first year—typically between weeks 1 and 3, weeks 6 and 8, and during month 3, month 6, and month 9. The good news: growth spurts can disrupt your baby's routine but they typically only last a day or two.
Signs Your Baby is Hungry
Fists moving to mouth. Head turning to look for the breast. Becoming more alert and active. Sucking on hands or lip smacking.
Babies that are less than 4 weeks old will wake up when hungry at night. Till they turn 6 months of age, they will be needing at least one feed at night.
If your baby hardly eats and the excessive sleeping continues, he could have low blood sugar. Signs of low blood sugar may include your baby acting jittery or appearing to be shivering. You can try gently pulling on his arms. If your baby does not pull back, it could be a sign of low blood sugar.
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.
Cluster feeding usually happens during the first 3 to 4 months. It's when your baby wants to feed even more frequently (sometimes constantly) over a period of time. It's very normal and nothing to be concerned about. Your baby may want to cluster feed during the day or night (or a bit of both).
