homeopathy! my son developed eczema at about same age. he was finally free of it by the time he was ~5.5 - after only one visit! and to think of all the things that we did before that! - we never did conventional "therapy" - hydrocortisone or any other steroids, but have tried a lot of food and water tricks and eczema would always come back. here is how to find the good one close to you:

since this is constitutional treatment - ask - they'll explain how it is different from acute - i would not go to MD, OD, chiro or even ND who does not have all their practice set up around homeopathy and use it "on the side". just pick the one who has letters CCH (certifiedclassical homeopath)after the last name. if you are in the greater LA/Long Beach area i can e-mail you info on the one that i've used.
Good Luck
