Can a parent be a coach to their child?

This is a question that is often asked by parents when they are wondering if it is worthwhile to hire a professional coach.  Here is my usual response: A parent can be a good choice for coaching a young child.  The parent receives the coaching tips and support from a trained coach, and implements the coaching. The parent must be able to stick to the program and follow through in a consistent manner for optimum success.   For coaching of students age 12 and up, it is helpful to use an “outsider” as the coach.  It is difficult to play to role of parent and coach to a teen at the same time. What do you think about the parent as coach idea?
