When my DD was born she took 30mls for the first day, then 4oz until she was a week and a half old and then 5oz until a few days ago, she's now 3 weeks old n has been draining 6oz bottles for the past 2 days...I'm worried incase I'm over feeding her, she doesn't throw it up but she does spew a little bit but nothing major? Has anyone else's baby taken this much? (She's been formula fed since birth, aptamil)
