Hi, I have a 3 year old boy who weighs 36 pounds with a fever that has lasted more than two weeks now. It is accompanied with chills,cough,and loose stool, some vomiting, but I am mainly concern about the fever because he has had it for so long. I took him to the doctor and he does not seem to have an infection. He already finished a bottle of ibuprofen. Doctors say it's viral but is it normal for him to have 5 times a day for the last two in a half weeks?
