so my son is on isomil cuz any other formula makes his poop rocks and he gets extremely fussy and gassy

well lately he'll poop every few days and when he does its starts off hard and big to the point where we have to assist him by squeezing like a pimple to pop the poop out

he'll have 2 like that then it will get soft and he'll finish

im just really stuck on what to do and how to help my little man

he's 4 month old btw
