i had a similar poblem when i took my son snowboading last winter. he claimed the boys all did it instead of going back to the lodge to used the bathroom. i purchased a package of attends and made it clear that ifn it ocured again he would be wearing them until he decided he was adult enough to use the bathroom. well les than a week later after sledoing with a few friends he tried to was his wet clothes without my knowladge. i was furious and put him in diapers for a few days. his attituyde quickly changed after a few of the other boys noticed. i haven't had a problem since
