You can dream feed if youre too full or need the help to sleep.

I wouldn’t unless the medical team was concerned about them putting on weight

Some babies have issues at birth, such as being premature or just on the small side. Sometimes in these cases the Drs will suggest waking them as they have little strength and need regular feeds. If all is well with baby though, then no, they wake when they’re hungry

If a baby is healthy then no. When they are asleep this is when they do all their growing.

Unless the bub is struggling to gain weight or needs to be fed at certain times for medical reasons, I let my babies sleep. Sleep is precious, and they wake when they’re hungry (unless a premmie or something else is wrong).

So long as your baby is a healthy weight, I would not wake the baby for a feed.

Whether you should wake a sleeping newborn for feedings depends on the baby’s age, weight and overall health.

Most newborns lose weight in the first few days after birth. Until your newborn regains this lost weight — usually within one week 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.

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. While waking up a sleeping baby might seem like a bad idea, frequent feedings early on are important for a couple of reasons:

Crying is a late sign of hunger. The sooner you begin each feeding, the less likely you’ll need to soothe a frantic baby. Look for early signs of hunger, such as stirring, restlessness, sucking motions and lip movements.
Frequent feedings support early breast-feeding. If you breast-feed, frequent feedings will help you establish your milk supply. Babies also are more likely to nurse repeatedly in a short period of time (cluster feed) if they have gone longer stretches between feedings.

My answer to this is no. But it really depends on your baby and if they have any health issues, like being born early

Some premmie babies need waking to feed. They sleep a lot and font wake themselves. Other babies, I wouldn’t

I never did it and I don’t think you should.

From day 1, I was always told never to wake a baby from his sleep ( hence let sleeping dogs lie phrase ) and only if for example they oversleep ( say 10-12 hours ) that you are concerned then lightly stroke their face to wake them up for a feed. I would check with your doctor or childhood nurse if you think there should be a concerned , otherwise let them sleep .
