6 month shots

Dazia

My LO had his 6 month shots 3 days ago. he's been really fussy. I've gave him Motrin twice in the last 2 days. (he had a fever the day after shots) anybody else experience this and everything was okay? it's really starting to worry me. he's always so happy and silly. he was a little fussy before from teething but it has gotten worse where he wants me to hold him all day everyday.
