Grumpy Lu

We are seriously at a loss of what to do with the Lu?  He can be such a good, happy little guy but the tiniest little things set him off and when he's mad, look out!  We are having the hardest time trying to figure out what he wants/needs.  He will stand right next to me and scream the most blood curdling scream ever, head thrown back with tears and snot and all.  He is so loud that you can hear him clear across the house!  I pick him up to calm him down and he screams louder and bucks and kicks and throws his entire body back.  Like he wants to be picked up but don't touch him at the same time.  I immediately put him back down so that I don't drop him instead.  It's hard to hold on to that wild little man!  He's fed, has a clean diaper, has his binky and blanket and still chooses to just be mad.  I have gotten pretty good at ignoring him when he's in these moods.  They seem to be getting more frequent though and are starting to wear on me now.  I sometimes wonder if he's not feeling well, like maybe an ear infections or something.  I've taken him to the doctor twice for this before just to find out that he's fine, just grumpy.  Now I'm wondering if he might be having growing pains?  I don't know.  All I know is I wish he would calm down a little bit.  Sometimes when Daddy picks him up he will calm down, like flipping a switch off. He's spoiled I suppose. I really think that that is all it is. How do we cure that?!  He's definitely giving us a run for our money!  Dr. Fullmer wasn't kidding when he told us that he heard child number two is always worse, haha.
