My sister's three small children all suffered with itchy eczema, until she started giving them Moducare, which is plant sterols and sterulins. I don't remember how much she gave them, but I believe it was the recommended dose for small children - ages 1 1/2 and up. It's a tasteless powder that comes in a capsule, so you can mix it with applesauce or juice. All the eczema issues resolved. She stopped giving it to them after about a year or so, and the eczema never came back.
Moducare also greatly helped an asthmatic child who was told by his dr. he'd have to be on steroids for the rest of his life. He never did take the steroids, and the asthma got better.
