Hi, may I answer your health queries right now ? Please type your query here...My 9 months old son this morning had a dark silver, aluminum kinda paint like stool but only on the surface, the inside was a regular stool color. This is a second time that happens, first time about a week ago. He is perfectly fine, eats everything, doesn't complain. He usually has bowel movement almost every day but he's a little constipated. Why did the stool come out silver? Thanks
