My dd is 9 1/2 weeks old and has reflux so she spits up quite a bit. I have changed my diet to help reduce the acid in my breastmilk and that seems to help. My concern now is that the last two days she has had spit up come out of her nose. When this happens, it only comes out of her nose - nothing comes out of her mouth. She did this once yesterday and once today. Should I be concerned or is this normal?
