My son has always suffered from eczema, very bad as a baby/little kid (until we took him off of milk and gluten for 4 years). Now he mainly gets it on his left wrist, side of his left forearm down to the elbow and on the outer part of his left knee. It just started showing up on the side of his left butt cheek too. I use cortisone and it helps tremendously but I have to be constantly checking him. He won't say anything until it's really bad and itchy. Does anyone have any recommendations for what kind of bath soap he should use? He uses Oil of Olay bar soap but I'm wondering if there is a better choice. Google searches are not coming up with anything specific.
