So many titles...so little space.

So what do you do to a little boy that throws his sippy cup at a door and shatters it??? That's been my dilemma all day!! The door going out to our former three seasons room (now converted in to Chad's office - just need to install permanent heat) is double paned glass with wood surround and he literally shattered one of the panes of glass - of course, it was the one pane with the etched design in it. Kale was SO sorry that he did it and sat on the floor (without us even asking him to) and said he was sorry over and over again. Then in his sweet little voice he says to me "mommy, you buy new door?" Needless to say, we had a VERY LONG conversation about the importance of not throwing our toys!!! Amazingly though, I kept my cool when I could have really gone crazy. I ask myself over and over again if ALL boys are like he is...he's not always destructive, he's a very sweet little boy...but when his temper flares you better watch out. Any ideas on how to better discipline are widely accepted!!! Time-out, sending him to bed, making him give hugs and kisses (which the girls probably dislike more than he does) when he's hurt someone's feelings, taking away toys...we've tried them all to no success. I made sure to take a picture of it to show him in the future (I'll add it to the stack) - so he can see just how long he will be working for "FREE" for us to repay us for the many things he has broken, because I'm sure this won't be the last!!! HA!! The picture does not do the destruction any justice.
