2 and a half yr old with eczema

He has a brother with more severe eczema I would say who is being helped by Dr. Flemming. But I figured I'd ask here for his younger brother. Could it be that I can use the same remedy? I'm just not sure.
His symptoms are dry skin. He scratches until he bleeds. He is itchy and scratches his legs while sitting on the potty, while in bed, sometimes during playing on the floor with toys. He must scratch and can't stop. His face is very dry and raw. He has only had one immunization at birth. Dry skin began at around 3 months. Dr. Flemming wanted me to begin with sulphur for my 5 yr old who has the same symptoms except that the 5 yr old has crusted honey ooze all over his face and the 2 yr old doesnt have this. I know eczema runs in the family. I had horrible hand eczema and my mother has extremely sensitive skin too, if that helps to diagnose. We try to stay to wheat and dairy free. He also still breastfeeds. Any suggestions on what to try for him. Oh and we've been steroid free for appx 10 months.
