My son just had an allergy food test and we found out he is allergic to alot of things. All children with allergies are different. You should really take your child to get tested have your doctor refer you to an allergist. My son is allergic to dustmites(which affects his ashtma and I think contributed to his infantile eczema), banana, chocolate, grape, squash, MUSTARD (which is found is ALOT of food as a spice), watermelon, COCONUT, peanut and lamb. He has been eating all these food for over 5 years and we never knew. I felt so bad for not getting him tested sooner. He has never had a serious reaction to these food just minor. Things like itchy skin, itchy mouth, gastro upset, diarrhea, possibly asthma and eczema. We use a cortizone cream for a few days durring a bad outbreak and use aquaphor daily especially after a bath to lock in the moisture and every time after he washes his hands. Put a small amount of cortizone on the affected area ( do not use on face or near eyes ) then put a thick layer of aquaphor over it to seal in the medicine. Do this twice a day for a few days to get the eczema under control then just use the aquaphor. You really don't want to use the cortizone cream all that much they are a steroid and will cause thinning of the skin and actully stop working if you use it too much. Good Luck!!
