Hi and big hugs, from a mum who's baby never drank more than 12oz of formula a day I understand! How does your lo behave when he's had enough of the bottle? Does He scream, arch, seem to be in pain? Any possibility of reflux? Reflux babies often feed when sleepy. My dd had silent reflux and would fuss and cry when feeding, refuse any more and cry when laid down, she never spit up at all, it was like baby heartburn x
