I think it depends very much on the child, the gym and the family. And perhaps what you are anxious about. If your child is young and wants you there, that's one decision. I have a 12 year old who could care less if I'm there or not. If you are worried about her safety, her coach's behavior, or another child on the team teasing or something, then that's a different set of factors. If you think the coach or gym won't communicate a potential injury to you, then I'd probably look for a different gym, but that would be me. Also factoring in there would be, what would you be doing if you weren't at practice and does being at practice impact other kids in the family? Even if my child wanted me there, if it was a negative impact on the rest of the family then it might be time to explore dropping off.
