Fussy Baby

Well, Andrew has been REALLY tuff the last 2 days. He is constantly crying. I am supposed to go to quilting day at a friends but I really don't want to go if he is going to be like this. I don't think they would appreciate it either-him crying constantly. I'm not sure why he's doing this because I don't think he is sick. I would say he was spoiled but he still cries even if I pick him up. What to do??
