Little stinker

Cooper has figured out how to pull himself up to standing.  And now, instead of going to bed like a nice little boy, he would rather pull himself up in his crib and stand there crying and hollering  for attention.  He has also been developing a little something in the last week or so:  his temper.  I would like to blame it on him not feeling well, because then I can hope that when he is feeling better, he will be back to nicer behavior!  His temper is unpleasant when he tries to arch out of his carseat when I am trying to buckle him in.  And it is unpleasant when I am trying to wash his hair in the bathtub and he doesn't want to lay back, or when we are trying to get him to go to bed.  It's the worst though when he refuses to hold still long enough to get his diaper changed; I'm waiting for my sweet boy to come back!
