Hi. My 20 week old DS has been taking Aptamil 1 since birth with no issues. However, for the last 2 weeks he has been having explosive poohs with every bottle (usually after around 3/4oz) and they're really runny/ watery. I would call it diarrhoea. And it's immediate every time.
The HV has suggested switching to a formula with higher casein protein content (rather than lighter whey protein as is used in aptamil 1). Her thinking is it will firm up the bowel movements as its 'heavier'. I was considering trying Aptamil hungry baby..?
Does anyone have any experience with this? Thanks!
