My 2 year old has been sick since early Friday morning. She started with vomiting through Friday evening with a low grade fever on Friday evening 101.5 taken in the ear. Saturday and Sunday she was complaining of belly pain low and had diarrhea no fever. Monday morning she woke up with 102 fever that rose to 103 in the afternoon stayed through the day and would spike to 104 at night. We gave her some Tylenol and it brought the fever down. This morning she still complains of belly pain and is running a temp of 101.5. She has had 2 courses of antibiotics in the last couple months a 10 day dose that ended 11/24/16 and a second 10 day course that ended 1/4/16 these were used to treat an ear infection. I am concerned about the belly pain and the fever coming after the vomiting and diarrhea but I don't know what it could be. I don't really want to have to put her on more antibiotic either as she has had 2 doses in such a short period of time. What could this be?
