At what age do babies start sleeping through the night?

My daughter is 4 months old and she's still waking up every 3 hours to eat. My friends tell me their babies are already sleeping through the night at 3 months, and I'm wondering if it's normal that mine isn't doing that yet or if there's something I can do to help her.

At 4 months, the digestive system still needs to eat every few hours, so the wake-ups are physiological and there's not much you can "fix." My niece slept like that until 5-6 months and then one day she just managed to sleep longer, without anyone doing anything special. What does help is establishing a consistent bedtime routine (bath, pajamas, whatever) so her body starts to associate that with sleep, but as long as she's hungry every 3 hours, she's going to wake up anyway. Patience is the only thing that works at this age.

Every baby is different, so don't worry if yours is still waking up every 3 hours at 4 months - that's completely normal and many babies don't sleep through the night until 6 months or later. At that age their metabolism is fast and they need to eat frequently, so your daughter is probably doing exactly what she should. What you can try is establishing a bedtime routine, keeping the environment dark and quiet, but honestly the best thing is to be patient because this improves with time without you having to do much.

Your daughter is within the normal range, even though waking up every 3 hours at 4 months is still pretty frequent. What you're seeing with other mothers is that many of them exaggerate or straight-up lie about when their kids started sleeping through the night, so don't let that influence you too much. Between 4 and 6 months is when a lot of babies start having the physiological ability to go longer without eating at night, but every baby has their own rhythm and it also depends on whether she's breastfeeding or bottle-feeding and how much she eats during the day. What you can try is establishing clear bedtime routines and making sure she eats enough during the day, but without expecting miracles at this age.

What actually works is making sure he eats enough during the day, especially before bedtime, because a lot of babies that age still can't tell the difference between real hunger and needing comfort. If you give him a bit more at the nighttime feed, some sleep a little longer (though honestly at 4 months it'll still be every 3-4 hours on average, so don't expect miracles). The friends who say their kids sleep through the night at 3 are probably just not hearing them, or they're giving you a very optimistic version of reality.

Are you trying to get her to sleep through the night or do you just want to understand what's normal at this stage?

Waking up every 3 hours at 4 months is completely physiological - her little stomach is tiny and milk gets digested pretty fast. It's not that something's wrong, it's that she still needs to eat frequently. What happens with your friends is there's a lot of myth floating around - some exaggerate, others get lucky, and some put their babies to sleep longer than recommended before it's time. Your daughter is perfectly fine where she's at.

Now, here's what nobody mentions: it's not a good idea to push for her to sleep through the night too early. At 4 months sleeping 6-7 hours straight would be unusual, and babies need to eat often. After 5-6 months a lot of them naturally start needing fewer night feedings, but that really depends on each baby. The only thing you can try is making sure she eats well during the day - babies who are satisfied during the day tend to sleep better at night, but it's not guaranteed. If you're breastfeeding, you'll notice she gets faster and more efficient at it over time. If she's on formula, you can offer her a bit more in her last bottle before bed, but don't get obsessed about it.

What matters is that your daughter is doing well, she's growing, and these wake-ups are what you'd expect. In a couple of months it's going to change on its own 🌱
