I'm sorry but hitting your kids DOES NOT equal well behaved children!
None of us are perfect parents but if we are doing it right then kids wouldn't act the way some of them do. We have a 12 yr old, who yes has that girl tween attitude but she's also a straight A student who loves to read and volunteer and I never spanked her. Explain that one.
I'm just sitting here at work holding my tongue listening to all my co workers talk about "busting their kids butts", and they STILL misbehave! Obviously it isn't working!!!!!
