C.S.
Yes, my third child has it now. Started with vomiting and then led to a long-lasting bout with diarrhea. I had never seen so much diarrhea in my life as what my 3 year old was producing! My 3yr old and 5 yr old both had it for a long time, probably 8-10 days. She was eating and drinking normally too. I think it's just something you have to wait out, but you may as well bring her to the doctor if they advised you to do that.
