Hi Ana,
Based on my experience, eczema is a symptom of a immune activation.
My son had a rash that i used special detergent, soaps, lotions that controlled it, but it never went away until I removed the immune activators in his diet (his was milk).
My goddaughter had extensive eczema on arms legs and trunk. Food changes (GFCF diet) helped tremendously. Treating for yeast helped also. Additional supplementation and immune support finally cleared it up. If you treat the immune activation, you will address the eczema as well as other problems/allergies that will develop from the same root of the problem. There is a book called "Healing the childhood epidemics", by Kenneth Bock that you can read about the protocol. I am not suggesting that your child has any of these later problems, but eczema very often is a problem with children who also have more compounded problems. As they address these imbalences and allergies trying to treat the more difficult gut issues, the eczema also goes away. This may seem all so confusing, but if you read and learn about immune activation/fungal overgrowths, it may become clearer. J.
