2 month old

So my baby is 2 months old. I have been getting a lot of different advice on what to do, just wanna see what other mamas say, or what other first time moms have done. My baby will take 6 Oz of formula before bed time. We are trying to get on a routine. I know the older generation has had different information about newborns than this generation. Do any mommas let their baby sleep and them tell you when they are hungry? Or are you still feeding every 2 hours. My mom thinks I need to be feeding him every 2 hours even though he’s back and beyond his birth weight. I just want some opinions from some young mamas around 24 years of age.
