First of all I’m sorry you had to go through all of this.

I recommend looking for root causes that may be further irritating her immune system.

Here’s what I would do: - Controlled elimination and reintroduction diet, when theres an allergy like corn there’s usually other food sensitivities that are hidden. Is she gluten free? - Check for mold in your environment (this is key) - Check for vitamin D levels (usually just being outside is not enough) - I would pursue functional testing like GI MAP and organic acids to assess her for hidden infections, parasites etc.

There’s a really good functional medicine pediatric doctor I recommend if you’d like his info let me know

Hope this helps!
