Breastfeeding my baby 3wks4days,low milk supply,wil my supply increase ever?

Are you giving her formula in the bottle? That could be the problem to low milk supply. You should let her nurse anytime she wants to, it will increase your milk supply telling your body to make more milk because she is eating more. It sucks and is very tiring. Here's what I started doing at night.. I nurse lying down, I get sleep and so does my baby. When he wakes up I just give him my boob and go back to sleep. I love nursing that way.
