A: If he is drinking the same volume of breast milk in a bottle that he drinks at the breast, he should not be hungry. Most full-term babies who are 2-months-old will take 4-5 oz per feeding and those at 3-4 months old will take around 6-8 oz per feeding. It is possible he is just protesting the bottle itself because he is not able to nurse. I suggest letting someone else handle the bottle feeding while you sneak out of the house for an errand or a workout! He will be more accepting of a bottle from someone else.
