Oatmeal allergy

Brianna • 🇨🇦•29•Mom of Scout and Willow

10 days ago I introduced oatmeal to my LO and within 72 hours she developed hives, we stopped solids and went to unscented laundry detergent in case that was the issue and I read that reactions to oatmeal were rare so 2 days ago we reintroduced oatmeal and they came back and now there's more! I'm making a doctors appointment tomorrow for her but now think she could have an allergy to oatmeal. She has had the hardest time getting onto solids, so far we have 2 foods that haven't given her a bad reaction. Anyone else's baby get this reaction from oats? I mill my own for her so it's not even store bought baby cereal.
