Don't interfere

Parents, if you have a kid playing some kind of organized sport or activity you have to let the coach or instructor do their jobs. Not all coaches and instructors are great at what they do and we should all understand this. If you do your homework and investigate the program you will have more that enough information about the program to know if you are comfortable with it's instructors. If you don't feel that they are good enough to teach your child then do not enroll. If you are comfortable in their coaching ability and knowledge of the activity then by all means sign them up and let the coach coach.
