L.D.
My daughter has EE and is allergic to milk,egg,peanut,soy,corn,wheat,oat and beef.
On the bright side you will become a great cook. If his only allergies end up being milk and egg. all you have to do is cook normally and use rice or soy milk in place of cow milk and use the ener-g egg replacer. The diagnosis of ee just keeps flags up for more allergies otherwise they are treated the same as kids with food allergies with or without ee.
Just today I bought a homeopathic treatment at sprouts for my daughter for dairy allergy. It is basicaly desensitization for the allergy. Not recommended by conventional allergist, but I am not too conventional. I believe the body can heal itself given the right direction to do so.
best of luck to you.
