We didn't hit our children; They don't hit their children. None of them were "mouthy little brats," Marci, and our family is a very close, loving one (in spite of not being geographically close). "Wait till your father gets home" sounds like a great way to make kids resent, fear, and hate their fathers. Is that what you consider a good way to raise children?
Obviously, kids have to be stopped from wrong, dangerous, or obnoxious behavior. (I'm talking about normal kids, not those with psychiatric problems who have to be treated by professionals.) But such behavior can be corrected in many different ways than physically striking or threatening them, or making the other parent the villain. In our case, the usual punishment was "go to your room." That was enough to get the message across. Or taking away privileges, making them correct the harm them have done, etc. Assaulting them, and yes, even a spanking is a kind of assault, is never necessary or a good idea.
