I agree with everything you have posted. I would also recommend that they see a holistic physician that provides natural Medicine/vitamins to help heal her immune system.
I have multiple Environmental and food, allergies (35 food allergies), Epilepsy, asthma, leaky, gut, fragile bones due to high doses of steroids and chemotherapy as a child for 10 1/2 years. My holistic physician has helped me more in the last 2 months that any MD has!
