I think the chapter on spanking is pretty good, he has pages and pages of DON'T spank and this is why and then a couple of pages saying that he knows that no matter what people will still think it is ok to spank so he wants to make yourself look objectively at the spanking. The things he says is Examine your overall parenting style, Examine your relationship with your child, Determine where spanking fits in, Don't spank in anger, do not violate your child (I don't think this is possible with spanking, but it is a good message none-the-less), Explain the spank, Ask yourself "Is spanking working", Examine the time you spend with your child. I think that part of the chapter in spanking might even be the best really.... cause a spanker usually has issues with their parenting, their relationship with the child, their emotions, their self control, etc. So by getting into the more mainstream crowd, Dr Sears is opening up a chance to try something different by getting into these spankers heads.
He never says that people should spank, in fact he starts out that section saying that he firmly believes that spanking is not good. I really look at that section as a way for him to show spankers that really the discipline that they are doing just isn't working. I honestly do not think that anyone could spank and have a good relationship with their child, not do it in anger, not violate their children etc.
I see that chapter as Dr Sears working a little magic on the people stuck in spanking...those people will read that chapter because they do believe in spanking and then might realize that maybe it isn't the best because they do spank in anger or whatever.
Did that make sense? I feel like I totally rambled.
