Smack sound so cruel (sounds like slap), but I am a firm believer of a tap to the bottom under the right circumstances and as a form of loving dicsipline. My parents did it to me and my sisters when we where growing up and although at that precise moment it seemed unfair and hurt like hell, it was done with so much love that I don't have bad memmories or connections to being tapped on the bum. Granted my parents NEVER hit us in anger and NEVER bruised us and NEVER BUT NEVER slapped us in the face. Always a tap on the bum and then you were left to cry it out. After that you would be huged and you would say that you were sorry and that you understand why you have been tapped. You would get a HUGE hug and lots of I-love-u's and then it's over. (if you are lucky - ice-cream)
It is the way I am going to raise my daughter. I would try other methods to (no TV ect), but tapping the butt would be my choice. I would also wait until she is big enough to understand why she is in trouble, I am not hitting my six month old!!
I know some of you would not agree, but then I don't agree on not tapping a bottom. PLEASE, I don't approve of slapping or hitting with an sjambok or a fist. I know that there are some ppl that treat their childern like adults by hitting them to hard. I hate that also.
