If your child isn't a newborn I'd give Tylenol and a bath and see what happens. 100.4 isn't that a bad of a fever and my pedi told me once he can't do anything more that I can unless the fever is more than 103ish and Tylenol won't bring it down.
Thank you guys. He was more sleepy this evening than usual but not cranky at all very smiley. He threw up quite a few times today but that's hard to judge with him as he does it a lot anyways. i was getting him ready for a bath anyways so we did that and some Tylenol. I'm wondering if a tooth is finally going to pop through as he's had fingers in his mouth all day.
