I'm just curious as to what other gyms policy is for allowing parents to watch. As of now, my gym allows parents to stay. The problem I find is that many try coaching through the window or from the second floor! I think it might be a distraction and there are some kids who turn around to get mom or dads reaction after each skill. We are making some renovations and are thinking of a 2 way mirror.. parents can still see, but kids won't be distracted. Is this a good idea?
