Feeding baby

Depends on the baby. Some around 2 mths can slp thru the night. Some around 18 mths then will master it.

There's no right and wrong answer. It's entirely up to you. Some parents prefer waking their LO up every 2 to 3 hours and some do on demand. For me is i pass my LO 1st month benchmark and he must not be at the low percentile of weight, as long as he's gaining weight steadily then i wouldn't wake him up every 2 to 3 hours. And again i must emphasise, it's entirely up to you. You do you. Hope this helps.
