Why Do Children Lie? A Developmental Approach to Understanding.
Hi everyone,
I’m so glad you’re here. I’ll be sending out a monthly newsletter focused on topics related to child development and emotional well-being.
This month’s topic is something all children do at some point—lie. It often catches parents off guard, especially when it first appears in the preschool years (or even earlier if there are older siblings in the home!). However, lying is actually a developmentally appropriate way for children to test their growing cognitive abilities. In this newsletter, I’ll explore why young children lie, how this changes as they grow, and how we can support the development of honesty.
Lying in Young Children (Ages 3–6)
Early on, children do not yet understand that we all have separate thoughts and perspectives. As they grow, they begin to develop what is called Theory of Mind—the ability to recognize that others have thoughts and knowledge that are different from their own. This cognitive milestone typically develops between the ages of 3 and 6.
As this ability emerges, children often “test it out.” They may say they didn’t take a toy or eat a cookie when they did. While this can be frustrating, it is actually a sign of cognitive growth. They are learning that they can hold information internally and share (or not share) it with others.
At this age, it is important not to respond with strong reactions or harsh punishment. Instead, gentle curiosity, a calm tone, and even a bit of humor can go a long way. When possible, try to focus on the feeling or need behind the lie.
For example, if a child insists they hear the ice cream truck when there isn’t one, this is often wishful thinking—they want it to be true. In these moments, you might respond with empathy:
“It sounds like you were really hoping the ice cream truck was coming. I would love that too.”
It’s also important to actively praise honesty, especially when telling the truth feels hard. If a child admits to spilling something or breaking an item, acknowledging their honesty is powerful:
“Thank you for telling me the truth. That was brave.”
You can still address the behavior while reinforcing that honesty is valued.
Modeling Honesty
Children are always watching us. When they hear adults tell “white lies,” it can become confusing. Is lying okay sometimes? When? With whom? Being mindful of how we model honesty helps provide clarity and consistency for children as they develop their own moral understanding.
Talking About Honesty
As children grow, modeling alone is not always enough. It becomes important to have direct conversations about honesty, lying, and related behaviors such as cheating. Clearly communicating family values and expectations helps children understand not just what is expected, but why it matters.
Lying in Older Children (Ages 7+)
As children get older, their reasons for lying become more complex. They may lie to avoid embarrassment, protect someone’s feelings, or stay out of trouble. In most cases, occasional lying is still developmentally normal.
As with younger children, empathy is key. Understanding the feeling behind the behavior helps children feel safe enough to be honest. Excessive punishment often leads to more secrecy, not more honesty.
Open, respectful conversations about family values—rather than authoritarian rules—tend to be more effective. Helping children understand that honesty builds trust and strengthens relationships can guide them toward making more thoughtful choices.

Stay calm when your child lies
Focus on the feeling behind the behavior
Praise truth-telling, especially when it’s hard
Model honesty in your own interactions
Have open, age-appropriate conversations about honesty and family values
⚠️ When to Be Concerned
While lying is a normal part of development, there are times when it may be helpful to seek additional support.
If lying is frequent, combined with aggression, or paired with significant behavior changes, it may be worth taking a closer look. You may also want to seek support if the lying is connected to unsafe or risky behaviors, or if you notice a noticeable shift in your child’s personality.
It can also be helpful to reach out if you are feeling overwhelmed or unsure how to respond to your child’s behavior. Just like adults, children benefit from support at different times in their lives, and sometimes guidance from a professional can help families better understand what is going on and how to move forward.
If you have concerns about your child’s behavior or would like additional support, play therapy can provide a safe space for children to explore emotions, build self-awareness, and develop healthy coping skills.
