Understanding why children lie starts with a simple truth: it’s more common than you think.
When parents discover their child has lied, it can feel surprising, upsetting, and a little alarming. You might immediately wonder: Whoa… where is this coming from? We don’t lie, so why is my child lying? Or: Don’t they think they can be honest with me?
But before we jump to conclusions, it helps to pause and remember something very important: Lying is very common in childhood. In fact, it is often developmentally appropriate. You can read more about whether lying is considered bad behavior here.
Now, that does not mean we ignore it or excuse it. But it does mean we slow down our fears and judgments long enough to try to understand what the behavior is really showing us.
Because when children lie, they are not operating from the same place an adult does. Typically, they are not being intentionally malicious or manipulative in the way we sometimes fear. Much more often, they are using lying as a reactive, immature, almost clumsy strategy to handle something they do not yet know how to manage more directly.
The lie is the behavior we see on the surface. But underneath it, there is a feeling, a need, or a struggle that makes the lie feel useful in that moment. And when we understand that we can respond in a way that is much more effective.
Why Children Lie: The Three Most Common Reasons
According to Dr. Siggie, children typically lie for three common reasons:
- To avoid discomfort: Getting out of tasks like chores, homework, or hygiene.
- To escape trouble: Denying actions to avoid consequences, disappointment, or shame.
- To seek validation: Exaggerating achievements to feel powerful, competent, or worthy of praise.
While every child and every situation is different, here are three very common reasons children lie.
-
To get out of doing something they do not want to do
Your child does not want to… fill in the blank: brush their teeth, clean up, do homework, or go take a shower. And instead of simply saying, I don’t want to, they come up with a story.
“I can’t find my toothbrush.”
“I already did it.”
“We didn’t get homework today.”
“I didn’t hear you.”
The lie is an attempt to avoid discomfort, delay a task, or get out of doing something they do not feel like doing. And if we are honest, isn’t this deeply relatable? We all occasionally do not want to do something, we all resist discomfort, and we all look for ways to avoid tasks that feel boring, hard, or unpleasant.
Of course, that doesn’t make the lie okay. But it does help us understand it a bit more.
In moments like these, your child does not yet have the skills to say honestly, “I don’t want to do this,” and tolerate the fact that the answer will likely be, “I understand, and you still have to.”
Instead of focusing only on catching your child in a lie, we want to help them name the truth underneath it and face the inevitable task. We can do this through humor or through open and honest conversation:
And then we can work together to find a way to get through it without it feeling so hard.”

To get out of trouble
They broke something.
They hit their sibling.
They took something that was not theirs.
They ignored a rule.
And when they sense that consequences, disappointment, or disapproval are coming, they panic and deny.
“No, it wasn’t me!”
“I didn’t hit him.”
“I don’t know how that happened.”
“But she told me to do it!”
Again, when we allow ourselves to slow down and reflect, this is a very relatable reaction. None of us like getting in trouble. Most people do not enjoy feeling ashamed, exposed, or blamed.
Children are no different, except they have far fewer emotional tools for handling those feelings, so they lie. Not because lying is a good strategy. Not because they are bad. But because in that moment, avoiding the truth feels easier than facing the coming discomfort.
This is why shame-heavy responses do not help and traditional punishment backfires. Read more about why punishment backfires here.
When children are already afraid of getting in trouble, more anger or shame makes it feel even less safe to be honest. And when honesty feels unsafe, lying becomes more likely.
That does not mean there should be no accountability. There absolutely should be. But accountability works best when it is paired with emotional support and understanding.
-
To feel praise, power, or competence
Children also lie for a reason that can be easy to miss: they want to feel good about themselves. They want praise. They want to feel impressive and impress you. They want to feel capable, powerful, or admired.
So they might exaggerate.
“I did it all myself.”
“I was the fastest.”
“I got every answer right.”
“No one helped me.”
In these moments, the lie is less about deception and more about identity. The child is trying to create a version of themselves that feels strong, competent, special, and worthy of your approval.
And again, this is so very human. We all want to feel good about ourselves. We all want recognition. We all want to feel special in the eyes of the people who matter to us the most.
So the issue is not the desire for praise or power – those are very normal wants. The issue is that the child isn’t reaching for them in the healthiest way. Instead of reacting only to the falsehood, we want to respond to the underlying need.
But here’s a really important question: Are you also proud of you?
Let’s think about ways you can feel proud of yourself without making up a story.”
Why This Matters So Much
When we focus only on the lie, it’s so much easier to respond only with anger, lectures, and shame. But when we pause to ask, What is underneath this? we can respond in a way that is clearer, calmer, and more effective.
We widen our lens and address both the outer behavior and the inner experience. And when we do that, we help our children tell the truth because communicating honestly becomes the easier route to take.
Over time, your child becomes more able to say what is really true:
“I didn’t want to.”
“I was scared to get in trouble.”
“I wanted you to be proud of me.”
And those are the deeper truths we ultimately want to help our children express.

Frequently Asked Questions
Why do children lie to avoid getting in trouble?
When children sense that consequences or disappointment are coming, they panic and deny, not because they are bad, but because avoiding the truth feels easier in that moment than facing the discomfort. The solution isn’t more punishment; it’s making honesty feel safer than the lie.
Is it normal for children to lie?
Yes. Lying is very common in childhood and is often developmentally appropriate. Children are using lying as a reactive strategy to handle something they don’t yet know how to manage more directly.
Why do children lie about small things that don’t even matter?
Often because the lie isn’t really about the thing itself; it’s about avoiding a task, seeking praise, or feeling in control. When you look past the lie to what’s underneath it, the behavior usually makes a lot more sense.
How should I respond when my child lies?
Instead of focusing only on the lie, try to address what’s driving it. Name the feeling underneath, hold them accountable without shame, and help them practice saying what’s actually true. Over time, honesty becomes the easier route.
My child lies constantly. When should I be concerned?
If lying feels frequent, persistent, or is creating real problems at home or school, it may be a sign that your child needs more structured support; not just in the moment responses, but a fuller understanding of how to build honesty, connection, and emotional safety at home. That’s exactly what Dr. Siggie’s parenting courses are designed for. You can explore them here.
