Do your kids lie to you? OK let me re-phrase that, do your kids breath in oxygen? The answer to both is yes.

Kids realize early on that Mommy and Daddy can't read minds and they can say things that aren't true and get away with it.

The first lies are usually ones of denial and they can't start as early as two years of age

By the time kids reach 4 years old they're really starting to get the hang of telling tales, and not just to their parents.

When children reach school age they learn how to build up a lie by developing follow up answers to questions designed to expose their guilt.

My mother had a great gimmick to get us to confess when we were young kids, check it out in the videos below along with the results of a study on whether parents can tell if their kids are lying.
