7 month old baby with severe eczema

My infant son has had eczema since he was 4 months old. I knew he was sensitive to dairy as I could turn his reflux on and off by consuming dairy myself - he would get the protiens through breastmilk. Breastfeeding did not go well and despite weekly visits to the lactation consultation and a whole lotta effort, I ended our bf relationship when he was 5 months old. Between 4 and 5 months the amount of cow's milk based formula he received increased until it was his entire diet. Through this time his eczema continued to get worse. The rash began on his face but has spread through his trunk, all over his forearms, legs, and even in the diaper area. The rash itself does get flaky from time to time, but is more red and inflamed than scaly. His head is covered with re-curring cradle cap. Poor little guy.
We have been seeing a Naturopathic doctor and she has used NAET to eliminate his dairy as well as dust mite allergy. This has not cleared up his eczema and the Computerized Electric Dermal Screening did not reveal anyother serious sensitivities.
He is currently being moisturized with Unda Zalf 270, Unda cicatrisan,St. Francis Red Clover Plus, Vitamin E, and Aveeno baby lotion - not all at the same time of course.
He has been given Thuja occidentalis 30C as a homeopathic, but this did not alleviate the rash.
He has not had a reaction to any of the foods he has been given thus far. We have used hydrocortison at times when the rash has gotten very red and angry.
Also, he gets a tsp of flax oil and probiotic everyday.
It seems as though he is on such a great program, but nothing has helped. Any thoughts would be greatly appreciated.
