I need some help. My daughter has been struggling with the milk allergies so they started her on the nutramigen she’s been on this for about a week prior to that she had blood and mucus in her stool. We use the ready-made version because that’s what the doctors office gave us and now we have been strictly using only the can. This is the first time that I have seen her poop look like this is this something that I should be concerned about really need help
