I completely agree with Rhannie Q .
In addition, these lotions/creams are just masking the problem, not making it go away (solving it). Your son has eczema because of either a food ingredient (most likely dairy, soy or wheat/gluten or yeast) or outside allergens. Although this time of year, the outside allergens are very low.
I would either try to eliminate ALL sources of the food allergens (there are some hidden ones - look them up) Example: Dairy -- whey, cassein....
Good luck. When you stop the medicine, the symptoms will come back. Need to eliminate the source of the problem, not mask it.
I see a naturopath -- they can test for food sensitivities. It might not be a food allergy, but sensitivity.....
Hope this helps.
