How do you teach a kid to stop lying?

This really is not an easy thing to do but the best way to help the situation is to make sure the child realizes that there are consequences for lying to someone . If you can catch them in the act it is much easier then not knowing for sure if they have lied to you or not . One has to be consistent with punisment weahter it be going to there room to think about what they did or time out or not watching tv but consistecy is the best thing you can try to nip it in the bud before it become to big of a problem . All you can do is try your best and hope that your children will tell you the truth and when they don't let them know that you still love them but there are consequences for actions such as this .

It is hard to teach children about these things without practicing it. Children are pure and telling the truth is one of many things that we taught them. I also believe that when I was a kid, but when I started to understand things, I learned that adult people does the lie, so the adults that should have become my role model have taught me something different in practical.

Well, I don't have any kids but plenty of nephews and nieces. I was taught not to lie and if I did the punishment all depended on where I was and who was doing the punishing. I either ate soap or lard and got a spanking,grounded,chores,or preached at about the good the bad and the ugly about lying and what harm it can do. No matter if it was granny,mom,stepdad it was never easy. I found it best not to lie but my sibling still got into trouble. Once was usually enough to make me learn a lesson.
