Our EBF son had bad diaper rash because of how many bowel movements he had. Our ped recommended Evivo and it has cut down on his poops and therefore his rash has completely cleared up! Only thing is it is so difficult to get him to take it and keep it down. He hates the taste of it. Wish it could be mixed in a full bottle instead of a tiny stopper that he spits out. Seems to get enough down to make a difference though!
