I pull them up quick smart. And If my kid ignores me, or fails to respond, or goes and does the same act again, then they may actualy end up in trouble, because that is not acceptable at all. Then it is not just about the 'roar' (which may possibly escalate) but it is about my authority, and my kids disregard for it.
I agree with you on this 100% Misty. Whether or not my child listens to me in the playground is not negotiable for me. I don't care how much fun my girls are having, if I think something is going too far towards danger then they have to listen to me, and they have to listen first time so I wouldn't hesitate to pull them up on something like that, and go home if they continued to not do as they were asked.
