This thread is twisting me in knots. I finally decided to respond.
Do I think kids that age are old enough to be left alone at sports' practices? Yes.
Do I think many kids behave better when their parents are not around? Yes.
Do I think parents should drop off and pick up on time (Or let the coach know in advance when they will have issues)? Yes.
Do I think there should be penalties for those who routinely pick up late? Yes.
Do I think there should be penalities for the kids who do not listen/misbehave at practices? Yes.
Do I wish that at least a few extra adults would stay for every practice? Yes, Yes, Yes.
I witnessed an agonizing tragedy during soccer practice three years ago. Two people (a coach and assistant) would have been hard pressed to deal with it appropriately, taking care of a dozen 10yo girls who witnessed their friend's collapse, performing CPR, calling 911, trying to locate the parents... We were lucky to have four adults present, two had only just arrived.
For that reason alone, I wish all sports were treated like football is around here. Where all the teams practice on one large field at the same day and time so there are countless coaches and assistant coaches available; and there is always a trained medical responder, nurse or doctor on site.
I'm not trying to tell people what to do. I just needed to point out that while rare, these types of events do happen, and leaving a large number of kids on a field with just two adults may not be the best choice.
