My 7 yr old son has had a fever for 3 days. I've been alternating Tylenol with Motrin. It has only broke once then he spiked again. What is the proper way to alternate these meds. I don't think I'm doing it right.

I think if the fever has been going on for 3 days and you are unable to bring it down on your own, a trip to the doctor is in order.
