I totally understand. This is my son's first year, and we do our best to make sure he knows we want hime to have fun, if he wins awesome, but the most important is that he is happy and enjoying himself. My worst fear is he will burn out before he reaches Jr or Sr High, if hes not enjoying. On the other hand I do stress over the same issues but try not to let him know or see it.
We all just want happiness and success for our kids.
Good Luck everyone with the rest of the season.
