Check Your Reaction
Have a tendency to overreact to bad behavior? Your dramatics may be encouraging your child to tell a lie. He doesn't want the wrath of Mom when she finds out that he flunked his science test, so he'll lie—and continue lying—as long as that threat remains. "If you react with anger or rage, your child's lying will increase and go underground," Walfish warns. "Your goal is to have open, honest communication." Check yourself and tone down your reaction so your child isn't scared to tell the truth.
