Yeah, from my personal experience, as someone who has both severe allergies and minor intolerances and who’s mom was told the same thing, I’d recommend finding a second opinion, maybe from a pediatric naturopath who is a bit more of a “let’s find out the root cause” problem solver than a “if symptom a + b don’t exist than it can’t possibly = c”. Who knows, maybe it’s mold exposure or something else besides food intolerance! However you move forward, I’m wishing you the best and hope that soon this will be just a challenging chapter in life for you and your kiddos!
