Milk allergy 😭

Well we are on this battle now. She done so good on her enfamil sensitive until ohhh 2.5 weeks ago. So we started Nutrimagen and she broke out in a horrible rash on her face and neck after just 2 ounces. Started soy yesterday. Anyone have issues with Nutrimagen and soy helped? I pray so I just want her to be able to eat normal again.
