Girls, hello))) We're newbies in IV, older children on GIV were. So I want to ask. Is it normal for a child to have regurgitation and stool with some metallic smell? It reminds me of the smell of a totem and so on. And also, sometimes there are white hard lumps in the stool, like crumbs. Is this normal?
