My 6 year old son won most of the tournaments he entered as a 5 year old in the D brackets. This year, the coach has him in an A bracket. He is having trouble in this bracket this year but we kept telling him that it is only going to make him tougher. I think the coach is now going to put him in a B bracket so that he can have some success so he doesn't get too upset. He really has a problem with losing. We will see how well it goes.
