My 4 year old DS has recently started handling his anger very badly... He has ripped up a book, thrown things, tried to kick me or DH, and finally, last week he actually punched a wall(!) when DH wouldn't take him for an ATV ride.

What are your tips for getting LO's to properly handle their anger? And what do you do when LO is angry?
This is new to us because he actually has never been a big tantrum-er and would put himself in time-outs if he needed a break.
