Hello Mam / Sir , My baby is passing black stool after we change his formula from Aptamil to nan pro is it normal ? He is not showing interest in feeding since september so we thought to try some other brand but he is still not getting hungry any suggestions please?

A. No formula brand does change the colour to green and grey in general but it has got no connection with changing the brand of formula that you were giving maybe you are giving any iron supplement or you may have started lately that is why the colour black could possibility be seen and if your child is not liking to have it feed maybe the child is having its teeth now which the child may be refusing to it
