and now has a fever? Last weekend my two year old was throwing up and had diarrhea and was complaining that her tummy hurt. Well a few times a day since then she will come up to me and tell me her tummy hurts and will hunch over. She has been super grumpy all week and now tonight she has a low grade fever. What do you think it might be? Should I take her to the Dr. or wait it out?
