My bb now 18 days, weighted 3.49kg when he was born. Now eat 100 ml (~3.5 oz) mixed with formula and my milk coz he does not know how to suck properly and made my nipples hurt. So i have to pump the milk out for him.
My baby also around one week old, 3.2kg also give her breast feed but not work. As i have sore nipples already so just let her try around 15mins each side and then give her milk powder, she also need nearly 3oz ar.
