I coached my child for a few years but realized that she responded better to the other coaches so now I step back and let them do the job, if they are available. It hasn't changed a thing and I probably enjoy watching more because I am not mat-side. It is a personal preference but if you do coach your kid it does require you to act like a coach mat-side and not like an idiot. Don't embarrass your child and don't embarrass your club. Someone said earlier it is an obligation to coach your kid, I would disagree. It is an obligation to help and support your child in every way possible. Sometimes that will entitle stepping back and letting the coaches do their job.
