I don't have kids yet either, but I do plan on it very soon. I'm engaged, about to be married, and I plan on having kids. So my fiance has a daughter. He tells her what's wrong and right to do. He shows her, but of course, sometimes when she does things that she knows she's not supposed to do, he'll give her a little spank. So I will follow that. That's what I would do when I had my kids.
