I've had to start doing this. In theory, I don't like sending them away when they misbehave because I want to work through it with them; negative emotions are acceptable, even if negative behavior isn't. In practice, though, I don't think I have the patience for it. I find I'm a much calmer parent if one of us leaves the room for a bit before explanations. The trick, if I leave, is keeping the kid from following me.I rarely raise my voice so when I do, everyone listens. If I am close to losing my temper, I tend to send the misbehaving and obnoxious child to their room. I tell them straight out that they best get out of my sight and stay out of it until I calm down.
