How much do your newborns eat ?

Gabbi
My baby just ate 4 oz at 1 week old! My pediatrician said the baby will let me know when he's full so that's why I don't take the bottle from him, he slept a good 4 hours so I'm just assuming he was really hungry for waiting an extra 2 hours to eat but man just a few days ago he only barely ate 2 oz. How much are your babies eating in one feeding?
