G.S.
My son also had a high fever after each one of his sets of shots (2 mo, 4 mo, 6 mo). He was also very fussy and uncomfortable for about two days after the shots. After his 6 month shots, he even developed a rash for a few days. We gave him Tylenol and Motrin consistently to make him more comfortable, until we got the sense that he was getting better. While it felt like we were overmedicating him, it was clear that he felt much better when he was on the drugs. Fortunately, everything normalized after about two days.
