Bottle for EBF babe

How many ounces are you giving your 2-3 mo old EBF baby in a bottle? My baby girl is 2 1/2 months and I've been giving her 4 ounces but she never seems satisfied.  Does your baby cry when the bottle is finished or do they seem content?  I go back to work in less than two weeks so I'm trying to get into a good routine. On a sidenote my pediatrician says I'm overfeeding her and she should be only getting 2 to 3 ounces 😳
