The Era of Spanking is finally over? What does the bible say about that?

The Bible teaches us to discipline our chidlren and train up a child in the way he should go. Some of the methods used for this involves "spanking." Society at large frowns upon this. But what does the bibles say about this and shoudl we obey Gpod or men when it comes to this?

The American Academy of Pediatrics to recommend, in a new policy statement published Monday in the journal Pediatrics, that parents not spank, hit or slap their children. This statement from America's leading group of pediatricians, with 67,000 members, is an update to guidance they issued in 1988 that recommended parents "be encouraged and assisted in developing methods other than spanking" to discipline kids.
