Dd has red blochy dry spots on her belly. I am not sure why or where this came from. She did have some dry skin lately but it was not accompanied by redness. It now looks sore. She has been being a little fussy for the last couple of days. She is 7 mo and has been tasting some different foods lately. She has tried avocado, banana, sweet potato, zucchini, applesauce. All were organic and I didnt have any reason to suspect allergy. No change in soaps, lotions, etc. How can I treat this naturally?
