A Parent's Guide to Lying and Age-Appropriate Consequences

As the primary role models in children's lives, parents and caregivers play a vital part in showcasing honesty. They also have the most influence on instilling a deep-rooted commitment to telling the truth. As children mature and acquire a more sophisticated understanding of social etiquette, parents must help children differentiate between little white lies told to spare people's feelings and downright dishonesty.

For maximum influence at each developmental stage, address the subject of lying in an age-appropriate way. Keep reading to learn how to respond when kids are caught telling a lie, including age-appropriate consequences for lying.

Why Do Kids Lie?

According to the American Academy of Child & Adolescent Psychiatry, children and adults lie for similar reasons: to get out of trouble, for personal gain, to impress or protect someone, or to be polite. At a young age, kids will experiment with the truth and continue doing so through all the developmental stages, with varying degrees of sophistication and elaboration.

Kids might also be more likely to lie if their parents lie to them during childhood. Research shows that when parents lie to their kids, those kids have a significantly higher risk of growing up with maladapted behaviors such as externalizing blame and telling lies to avoid consequences.

"Teaching children about the importance of honesty early and teaching them how to resolve situations so they don't need to rely on lying will ensure they will be honest—most of the time," says Victoria Talwar, PhD, associate professor in the Department of Educational and Counseling Psychology at McGill University in Montreal.

Toddlers and Preschoolers (Ages 2 to 4)

Because toddlers' language skills are just emerging, they don't have a clear idea yet of where truth begins and ends. At this age, toddlers also have a fairly shaky grasp on the difference between reality, daydreams, wishes, fantasies, and fears, says Elizabeth Berger, a child psychiatrist and author of Raising Kids with Character. "Strong emotions can make a 2- or 3-year-old insist, 'He ate my cookie!' when a baby brother clearly did not do anything of the kind," says Berger.

Remember that toddlers are trying to exhibit their independence, and they can make a power struggle out of any disagreement. So try a mild, diplomatic response that interjects doubt, such as, "Really? Then those must not be crumbs I see on your chin." Saying this helps avoid a battle of the wills.

Toddlers are too young to be punished for lying, but parents can subtly begin to encourage truthfulness. Consider reading a lighthearted book such as Nicola Killen's Not Me to illustrate the issue of truthfulness.

Around age 4, as children become more verbal, they can tell obvious whoppers and respond "No" when you ask simple questions like, "Did you pinch your sister?" Use every opportunity to explain what a lie is and why it's bad. Introduce the subject (ideally, soon after your child tells the lie so the memory will still be fresh). Start with, "Let's talk about lying and why it's not OK"

"It may not be a long conversation, but give them the message that honesty is important," says Dr. Talwar. In response to a lie, be firm and serious, and say, "That sounds like you're not telling the truth," or "Are you absolutely sure that's what happened?" Make it clear that you are not taken in by the lies, but move on gracefully after listening to and gently correcting your child. Avoid confronting the child further or digging for the truth unless the situation is serious and demands more attention.

School-Age Kids (Ages 5 to 8)

Children between the ages of 5 and 8 will tell more lies to test what they can get away with, especially lies related to school such as classes, homework, teachers, and friends. Maintaining the lies may still be difficult, even though they're becoming better at concealing them. "The regulations and responsibilities of this age are often too much for children," says Berger. "As a result, children will often lie to appease the forces that seem to demand more performance than they can muster."

But, thankfully, most lies ("We didn't get any reading homework today") are relatively easy to detect. Talk openly to your children and continue reading stories together, such as Be Honest and Tell the Truth by Cheri J. Meiners. Also, notice when a child is being honest and provide praise and positive feedback.

Most importantly, because school-age children are keen observers, parents should continue to be good role models. Be careful about what reflexive lies you may be used to saying—even something as small as "Tell them I'm not at home" when you are—can send a very mixed message to a school-age child. "No matter how much you talk about the importance of honesty, you undermine the message if children see you being dishonest," says Dr. Talwar.

But not all lies are all bad. Groundbreaking and widely cited research from the 1970s has shown that, in some instances, telling the truth is viewed less favorably than telling a lie, and that knowing when to tell a white lie is a signal of social intelligence.

As a parent or caregiver, you may find it especially challenging to explain tricky social situations where a white lie might be more appropriate than the honest truth. Consider when your child must offer thanks for a gift that they don't like. Help them focus on the positive aspects of the gift. Explain to your child, "I know you don't love your new sweater, and it makes your neck itchy, but think about all the hours Grandma put into knitting it. That's the really special part about this gift, and that's something you can honestly thank her for."

Tweens (Ages 9 to 12)

Most tweens are well on their way to establishing a hardworking, trustworthy, and conscientious identity. But they're also becoming more adept at maintaining lies and more sensitive to the repercussions of their actions—and they may have strong feelings of guilt after lying.

Forthright and longer conversations about honesty are definitely necessary, as there will be rare "little white lie" moments when some dishonesty is acceptable in order to be polite or to spare another person's feelings. When situations like this arise, be straightforward with your child to avoid sending mixed messages.

Start a conversation with, "You know how always telling your parents the truth is very important, right? Well, there are also times when it's important to be polite and not hurt another person's feelings. If we're visiting friends and they serve a lunch you don't like, it's not polite to make a big scene and refuse to eat. You should eat the food and say 'Thank you.' You're being a thoughtful guest who will get invited over to play again next time!"

Good role models are still crucial for your kids, so consider enlisting close family members or caring neighbors to guide your children through challenging social interactions. It's going to get harder before it gets easier, but there is a silver lining. "Children who have an established relationship with their parents, where they feel comfortable talking and disclosing information, are more likely to tell the truth," says Dr. Talwar. "But also realize that your children are not always going to tell you the truth. Taking a moment to think about why they are lying should help you respond to their lies appropriately."

Age-Appropriate Consequences for Lying

You may be wondering if you should punish your child for lying, and the answer is no, not exactly. While there should be age-appropriate consequences for lying, it might be best to consider them as opportunities to teach your child about the importance of honesty as opposed to relying on punishment, which can cause feelings of humiliation.

The problem with punishment is that it doesn't teach a child a lesson in how to correct and avoid a specific behavior. Instead, punishment uses power to teach a child fear. Studies have shown that punishing children through force and shame can have profound negative psychological consequences.

Try using natural or logical consequences to help your child learn a lesson about lying. In other words, if your child lies and gets caught, use that moment to dole out a consequence that fits the crime. For example, if your child lies and says they cleaned their room when they really just shoved everything under their bed, a logical consequence would be to pull everything out and ask them to start over and put their things away where they go.

Afterward, reinforce the lesson by talking with your child about why lying isn't so great. By showing your child compassion, patience, and a willingness to listen and communicate with them, they are far less likely to take up a habit of lying.
