The American Academy of Pediatrics does not endorse spanking or other forms of corporal punishment for any reason and, based on other evidence, states that spanking is not effective in promoting long-term behavioral changes in children. Instead the AAP recommends other forms of punishment, particularly time out, as it helps a child to understand what and why a particular behavior is inappropriate. The recommended time for a time out is 1 minute for every year of your child's age.What are you thoughts on this study? What methods of discipline work with your children?
