My soon will be 3 months tomorrow and he has a fever I don't know if i should be worried or if I'm just being paranoid. On Wednesday he had a temp of 99.6 it went away that night then last nighty he started running a fever again it is ranging from 100.4 -101.4 I have given him Tylenol it only seems to drop it .1 of a degree. He has no other symptoms except he has been more fussy and very sleepy should i call Dr. or wait and deer off he gets better
