5yo DD gets a high temp with every virus/illness, but will not take Calpol/Nurofen. Can't pin her down to get it in, nor a suppository. Offe it in squash but she only has a few sips. When her temp is high she vomits. I try to keep her as cool as possible and let her body do its job, but is there any danger in not bringing a fever down with meds? Her temps often hit 39.5, can reach 40, then gradually come down and sit at 38-38.5 until the fever goes.
