Question for you moms out there. I have a 2 week old and I usually feed him around 3 oz. and he does fine, doesn't spit any of it up and let's me know when he's had enough then falls asleep. However the lady at wic told me not to do that. So I started giving him just 2 and he's been super fussy and acts like he's still hungry. Should I go back to 3 oz or stay at 2 oz?
