Yup. Mine was fine after previous shots but had more night wakings the night after and a fever the day after 6 months shots. Was fine a couple days later. Gave him baby Tylenol when he had a fever and it made a big difference.

Ohhhhh ya!! Took my dude a few days then he was SO fussy. The shot really did a number on him. He seemed so upset and nothing comforted him. Took a week to get back to himself.
