Hi, my 2 year old girl got sick this pass tuesday night, she vomited and since then has a fever ranging from 99 to 103, she also has had a bad cough with a lot of phlegm and runny nose. We ve been alternating childrens tylenol and motrin. Is it normal for the fever to last this long? We took her to the pediatrician on wednesday, and they diagnosed with her a virus. She tested negative for strep throat. Thanks,
