What rules have a specific provision for stopping play early due to an injury? You run until the umpire stops play. Nothing more, nothing less.
Look it up....it's called the daddy rule...if I think my DD or even my DS is hurt bad enough, I as the dad will run on the field. I've been at games/court that my kids have been 'hurt' but, not so bad that they needed me. Believe me I don't baby my kids..as I wasn't babied. It's a game....I'll stop there before my rant. As a parent do what you want or not I don't care but, I will agree with stopping the play if a kid is injured at anytime. I'm out of this 'tough man thread'.
