For the first 3½ months, my son's poop was always yellow when he was on MMS Gold formula. Ever since I switched him to NAN Excella Pro, his poop has been green. I'm really worried. On top of that, he seems to be getting thinner, and his weight is not increasing. can I change back to MMS gold.

A. Okay so I must confirm this thing having grey to dark coloured green coloured motion as you mentioned can be associated with any formula brand that you are giving so if you feel that the child is becoming thin then you can switch to previous one that you were giving from the time of birth which is MMS what is the child is gaining a minimum of half a kilo kilogram in a month with a current milk that you are giving then there is nothing that you need to do it’s perfectly good and also the motion colour is very normal
