James is allergic to peanuts, tree nuts, dairy, soy, eggs, wheat, fish, shellfish, citrus fruits, stoned fruits, berries, olive oil, grapeseed oil, peas, sweet potato, potato, broccolli, squash, chicken, beef and pork. There are other things that were in his diet that caused milder reactions therefore difficult to pinpoint. We were going to go back to basics to see if we could identify what his other allergens were but before we got the chance he started refusing all food and will now only have neocate advance and raisins. If we do manage to get James to eat anything else it usually results in him being in pain screaming and pulling at his stomach for around 2 hours in the evening.
As you can see from my reply James has lots of allergies. They cause his eczema to flare but also give him stomach pain, mucousy nappies and his lips and face go puffy. We used probiotics for James when he had been on several course of antibiotics and kept him on them for about a year. We give James starflower oil as fish oil gives him stomach cramps follwed by several yucky nappies within an hour. We started using natural emollients for James's skin as he seemed to react to the ones he got on prescription after the first few days. We think he may have been reacting to the petroleum in them. We now use dermasalve baby and infant cream at the moment but have also found coconut oil good and amazingly James seems ok with that.
I am not sure what else I can say as from your post it looks like you are doing a lot already. If you have any other questions please don't hesitate to ask. I know how awful it is to watch your child suffer when all they want to do is scratch.
