A straight answer
My child lies about everything, even little things. How do I stop it?

Homework done? Yes. Who broke the lamp? Not me. Now even "I brushed my teeth" comes out as a story, and you've stopped believing any of it. It stings, and it doesn't mean you're raising a dishonest kid. Lying is a normal part of growing up, and it's one of the most workable things parents bring me.
What the lie is doing
Most lies from school-age kids have one job: staying out of trouble. A child who expects a big reaction to the truth learns that a story is the safer bet. Harsher punishment makes kids lie better, not less.
Make the truth worth telling
The fix is making honesty pay. When your child comes clean, you notice the truth itself, and the consequence for what they did is lighter than if you'd caught them in the lie. Skip questions you already know the answer to; a trap is one more chance to practice lying. How that fits your family is what we work out together in our sessions.
Keep your reaction steady
Your child weighs every confession against the face they expect to see. When their truth meets a calm face, even when you're upset, telling you starts to feel safe, and trust comes back in small pieces. My two boys are young, and I already know the look that says "it wasn't me" before a word comes out. You'll stay calmer when you've had some room of your own: a walk with a friend, an hour nobody else gets.
Why I do it this way
None of this is my opinion. Each step comes from programs with decades of research behind them. Here is the research, in plain words, with the study under each one.
Why harsh punishment backfires
In a natural experiment with 84 West African 3- and 4-year-olds, children from a punitive school lied about peeking at a toy more often than children from a nonpunitive school, and kept the lie up better under follow-up questions.
Show what honesty earns
In a study of 3- to 7-year-olds, the George Washington cherry-tree story, which shows honesty paying off, made children more truthful, while Pinocchio and The Boy Who Cried Wolf, which show lying punished, did not.
Lying grows with age; asking kindly helps
In 372 children aged 4 to 8, older children were more likely to lie, a normal step in growing up, and children told the truth more when an adult simply said they would be happy to hear it.

When to call your pediatrician instead
Talk to your pediatrician if the lying comes with stealing, setting fires, cruelty to people or animals, or serious trouble at school, or if your child's mood or behavior has changed suddenly. Those are a doctor's questions. This page is parenting consultation, not therapy and not a diagnosis.
