The Bible says spare the rod spoil the child! Spanking got a bad rap because too many people took it too far and children have been hurt. God will deal with those people and heal the children who have been hurt.
So yes, I believe in spanking with limits at 14mths, a very light spanking on the hand or bottom is perfect. The noise of your hand on the skin and the shock of it all will do more than the spanking. No one should ever spank a child except Godly parents and grandparents, because they will know the limits.
All life?s principals should be taught in the first five years and then developed and expanded on the rest of their lives. So you must start spanking early when justified and for every little thing. You must explain why they were spanked and always love them afterwards there should be no fear involved.
