There is a world of difference between abusing a child and smacking it. If these arseh*les know so much better than most parents they can borrow my three for a month ~ that'll teach them what real parenting is about
Sometimes there is no sensible alternative to a smack. Without a final deterent there is no discipline.
Sometimes a smack just makes me feel soooooooooooo much better. That is the wrong reason but without it I might well strangle them.
