I agree that it is not the referee's job ALONE to put a stop to this behavior. Usually if a child acts this way it's because their parents tolorate it. We had a 13 yr old boy in our club last year that wouldnt shake hands when he lost, then he would throw his headgear when he got into the stands. His parents were ok with that but our coaches were not. At our next practice our coaches told the child and the parents the next time he does this he is off the team. He also had to apologise to his teammates for the way he represented our club and HAS NOT done it since then. I think that it would make a huge difference if kids and their parents realized that this behavior was not going to be tolorated.
