my dd had a fever that high, actually it was 103 (rectal) after her 6 mo. appt and it was due to the shots. after her 9 mo. appt (with flu shot) she didn't get a fever that high. i was told by the dr. office that her fever wasn't considered high since she got the shots.
Definately use tylenol, you can alternate with motrin every 6 hours not 4. when taking a rectal temp you subtract 1 degree. if no improvement within 24 hours, call your pedi.
Re: My DS has a fever
Yes, I would. But I'd treat with tylenol and see if it goes down before doing anything about it unless there other symptoms as well.
Poor little guy Hope he feels better soon!
