Whenever I write about parenting stuff there is always the danger that the posts will give the impression that I think that the current topic is either the only thing that parenting is about or at least the most important thing. That's not true. Parenting is complex. It is a lot of things.
I have some general recommendations: if you are punishing (even if you are calling it "imposing a consequence") give some serious thought to whether there isn't a better way. I would like to suggest that you consider just accepting the behavior as a better way. Artificial consequences sometimes get in the way of kids learning from the natural consequences of their actions. Punishment will often result in kids just being pissed. If their behavior is satisfying a need (a way to deal wtih fear, for instance) then punishment may stop that behavior, but they will just find another way to address that need. Really, just stop punishing.
