I agree, a slap on the bottom is not needed. Most of the time the childs actionsrequires a swift kick in the butt.
The funny thing about this, or as I see it. After about 3 or 4 years old, a spanking is not required as much. Its the primal way of correcting a child that has yet to acquire the skills neededto under stand anything but a spanking. I used a slap on the butt with my girls when they were younger. I have not had to spank them in years. The last time they got a spanking would have been at about the age of 4. Now taking privileges from them is much more effective.
