since his shots on Friday. The first 24 hours I expected to be pretty bad but he just hasn't been himself since. He has been a lot more cranky and fussy. I am really hoping the shots coincided with some sort of growth spurt but I kind of doubt it. My son has never acted like this for more than a few hours at a time but it's been going on for 4 days now. Did this happen to anyone else after the shots?
