My son (when he was 4) used to destroy his toys. He would crash, smash, or whatever it took. He got some sort of strange thrill out of it. He even managed to break a bi Ertl tractor. He was told if he kept doing it he would not be getting any more new toys for Christmas or his birthday until it stopped. (just about the only time he gets new toys) He di;d1#82&7nt listen. On Christmas morning there were only books and clothes. He takes much better cafe of his toys now.
