The American Academy of Pediatrics has new advice: even if your parents did it to you, don't use corporal punishment when your child is acting out.  And they have reasons - one is, it doesn't work.

They point to studies that show punishment, in the form of spanking or slapping, doesn't work to change behavior -- the effects only last about 10 minutes. Then children resume the same, unwanted behavior that you wanted to curb.

Not only that, repeated use of corporal punishment can lead to aggressive behavior and negative parent-child relationships.

Many child rearing books - and, of course, your pediatrician, can recommend techniques that actually work.

So remember when your child pulls a prank, think twice before you spank!
