I found the best way to deal with behavioral problems is through positive reinforcement. I never yell, hit, spank, or punish. This only increases behavioral problems. When I was a kid, my parents did this to me, and is screwed me up pretty badly. I'll admit, I got most of my parenting advice from my husband. He is the best dad around. He spends constant time with the kids, and is a very loving, caring, and wonderful figurehead. Any sort of physical punishment will lead to more behavioral problems.
