I need help!

So Brok has this new thing he does where he literally screams bloody murder when he gets mad, & it is getting on our nerves. It doesn't matter if he is in the store, in his bed, on the floor, nothing, if something happens to tick him off, better cover your ears!

I do not know how to fix this. I have put him in his bed for time out where he just screams louder, I have said no, swatted him lightly, nothing phases this kid.

Have any other mom's had this issue!

He has also decided that he wants to wake up every 2 hrs at night, so not happening for me, I can't get up in the morning as it is! Anyone have any ideas why? I have let him scream but honestly, he doesn't stop. He was in his bed for 2hrs one day screaming so loud & I know he's tired but it seems like he jsut forgot that he likes to sleep.

The only place he will sleep is his car seat in the moving car but with gas how it is, well I am not going to drive more than necessary!!!!

HELP!!
Any ideas before we lose our sanity?
