Im glad I got beat too. It made me think twice and realize early that there were painful consequenses for my actions. I didnt care about material items so that time-out/your grounded mess was for the birds.
Heres the way I look at it... You are the damn parent, not their equal. If a kid feels like they are above you and nothing else works knock them back into their place. I would never say lead with a spanking (rewards tend to work better for a lot of people and its positive), but dont take it out of the equation. Kids respond to different punishments/rewards. Remember the punishment is not for you, its for them. You dont get to decide what works, you only get to decide what you are going to try to drive results. I just say what ever you chose, because it is up to you and your family, just please keep it within reason... and legal. A lot of parent suck at this. Beatings for spilling a beer by accident and time-outs for stabbing another kid. The end result are these emo kids in the mall drinking Starbucks and loudly calling their moms cunts for not buying them more black nail polish
On to the video, abuse and spankings are two different things. I saw abuse in that video on a phsyical and phsychological level. Im all for spankings, but you have to be able to control yourself as a parent. And why in the hell do you tape yourself beating your kid... who does that!?!!
