1. Only hit limbs and butt.
2. Not hitting excessive that leave scar, cause bleeding, or marks that last overnight. Thus, try not to use any spanking tools.
3. Must give warning and offer chance for compliance before spanking takes place.
4. Always give reasons before and/or after spanking.
5. Use it only if necessary, always other forms of punishment.
Kids these days are smart, I think my son is way smarter than we are when we were his age. However, intelligence is one thing, temper/attitude is another thing. I don't need my kid to be 100% obedient to me. It is neither practical nor reasonable. However, for things that matter. I must make my point heard and accepted. I just think spanking should be like a cop's pistol. You don't need to use it every time crime occurs. You may flesh it just for warning for compliance. But you shouldn't rule out of using it or simply not carrying it with you just because you are a good man and believe in peace and justice. Certainly, in some cases, a pistol should only be used when the cop's or others' safety is in danger, that doesn't apply to spanking. However, for other aspects of spanking, I think this analogy can be used to get points across.
