My daughter will be two in August, she has had the "stomach flu" for the last two months on and off but more on than off. But this morning she was throwing up white bile, then it turned yellow. She won't drink anything. I'm afraid she will get dehydrated. And she has never had the bile before, her stomach should not be empty. She ate dinner. Idk if it is her getting the virus again, or if she has soke sort of infection, or if maybe she has acid reflex?
