So, I keep reading that I can't overfeed my BF baby. Is there a reason for that? What about when baby is offered a bottle? Will he drink from a bottle even if he isn't hungry? My sister (who watches him twice a week) says that DS has never refused a bottle even if it has been less than two hours since his last bottle. He is 4 months old and drinks roughly 3-5oz bottles during the day. He will drink only two bottles if he decides to take a looooong nap.
