How long is everyone’s 3 week old sleeping ?

Are u formula or breast feeding or bottles of breast milk as im doing formula and pumped milk and have noticed a diffrance between the milks and midwifes told me breast milk is motabalised quicker so will want more feeds more often so to feed fornula at night since we started doing that she sleeps nerly 5 hours but she tends to eat bigger bottles before bed and in the morning

I'm breastfeeding and if she does settle which is a miracle I'll set an alarm for 2hrs, 45mins or 3hrs from start feeding and when she was weighed she was 10g away from birth weight. But my girl will sometimes wake up beforehand anyway. She's mainly awake than asleep!

I'm breastfeeding and mine sleeps anywhere between 1-3 hours at a time if he's in his crib, but he can go for 5 hours if we're co-sleeping! Luckily he smashed his weigh-ins early so the midwife said I could stop waking him up for feeds every 2 hours. As for the daytime, unless he falls asleep on the boob, naps are pretty much non existent and his wake windows can be as long as 7 hours, by which point we have a very overtired and fussy little man 🥴
Apparently around 3 weeks their sleep patterns change pretty drastically as they become more aware of their surroundings so they're more sensitive to light and noise but they will find their rhythm.

Once babies have reached their birth weight and the midwifes are happy about weight gain then they usually sign off on them having longer stretches at night.

Our little boy is 3 weeks and he averages 3-4 hours but he’s even done a 5hr+. He’s exclusively breastfeeding. As he’s still so young, health visitor has recommended not going beyond 4 hours until he’s had his next weigh in next week, just to make sure that he’s still gaining weight as before.

He’s probably lured us into a false sense of security as sleep pattern change is imminent so we could regress but we will see!

5 weeks here and breastfeeding.
Average an hour and a half between feeds. Got a 3 hour stretch this morning so hoping we get more of those 🤞🤞
Make sure you're eating enough and hydrating as will affect the quality of your milk and better nourishment means he will stay fuller longer
