I think my Lo is having his 4 month growth spurt because the last 2 nights I've fed him 20 mins on each boob (so 40mins) then he is still hungry so he is downing an entire carton of hungry baby milk (about 8oz/210ml) then going back on my boob for 5 mins before he is finally satisfied enough to sleep, if I don't do this he screams with hunger. Because I breast feed I haven't got a clue about ounces etc as I just feed Lo whenever he wants it and don't have a clue how much he's getting but I do know he feeds a lot! I know its only temporary as he did it for 5 days during his 3month growth spurt but he was only taking half a carton about 4oz then. I'm just a bit worried by the sheer volume he's having before bed and whether I might be damaging his tummy? Or if its ok as it will only be for another couple of nights then we'll be back to being ok with a boob feed?
