When I was in the hospital after I had her they provided the premade bottles of newborn enfamil which are two oz and they told me I'm not suppose to give her the full two oz even though she wanted it. When I got home from the hospital I started giving her two oz bottles and she did fine with it and acted full but now she is 10 days old and is still hungry after 2oz. I'm wondering if she needs a 3oz bottle now? Is that ok to give her this soon? Right now I'm giving 2oz bottle and breast feeding after but on the times I can't breast feed after should I give her a 3oz bottle?
