I'll never forget, at the first meet I ever attended, before my child was even competing, I saw a man walk up and lean over the barrier to yell "point your toes" to a girl competing on the beam. Even as a parent of a preschooler on preteam I knew that was bad form!
I enjoyed the article! If I were to add anything it would be to inform new competitive gymnastics parents that they should set up a meeting place with their child or tell their child to stay where they are after awards because they may not have any real supervision at that point.
