Our kids are soo much alike. My son also HAD eczema and I am breastfeeding. Now he no longer has it. I read about eliminating/ cutting back on certain foods and it has worked for me. I have cut cows milk out of my daily routine. I used to drink a glass every day for calcium. Now I take a liguid calcium supplment which actually tastes good because its lemon flavored. I also rarely eat ice cream. I am sure some small amounts of dairy still get into my diet from cheese etc, but the cutting back has made my sons eczema completly go away. I don't know what it is about cows milk that causes this. I hope this helps for your situation.
