Send us Fan MailWhy does your child lie, even when the truth seems obvious?Maybe your five-year-old insists they didn't eat the cookie while chocolate is still on their face. Maybe your eight-year-old swears they brushed their teeth when they clearly didn't. Or maybe your teenager tells you they were somewhere completely different from where you later discover they were.For parents, lying can trigger some big fears: Have I raised a dishonest child? Can I trust them? Should there be a bigger consequence?In this episode of Mom Doc Talk, board-certified pediatrician, parenting educator, and mom Dr. Kristen Cook explains why childhood lying is often much more complicated than simple dishonesty.Kristen walks through how lying changes from toddlerhood through adolescence and explains why imagination, fear, avoidance, executive functioning challenges, anxiety, trauma, and the growing desire for independence can all influence whether a child tells the truth.You'll also learn why some common parenting responses can unintentionally make lying worse, including yelling, labeling a child as a "liar," asking questions when you already know the answer, and creating an environment where admitting mistakes feels unsafe.Most importantly, Kristen explains how parents can build honesty through connection, accountability, emotional safety, and trust.Because the goal isn't simply to catch children lying.It's to raise children who feel safe enough to tell the truth, even when the truth is uncomfortable.What You'll LearnWhy children lie at different developmental stagesWhy toddlers may say something untrue without intentionally lyingThe important difference between imagination and deceptionWhy preschool fantasy is a healthy part of developmentWhy school-age children often lie to avoid consequencesWhy teenage lying often involves independence and privacyHow fear and harsh punishment can make honesty feel unsafeWhy children with ADHD may appear dishonest when executive functioning is the real challengeHow anxiety can contribute to avoidance and lyingWhy significant trauma can make dishonesty a survival strategyWhat prosocial or "white lies" look like in older childrenWhy asking questions you already know the answer to can create a trapWhy parents should address dishonest behavior without labeling the childHow modeling honesty influences children's behaviorHow to praise truth-telling without removing appropriate consequencesWhy connection and emotional safety are essential to building trustOrder Dr. Kristen Cook's BookParenting Redefined: A Guide to Understanding and Nurturing Your Child's Behavior to Help Them ThriveIf you enjoy Mom Doc Talk and want practical, evidence-based parenting guidance with compassion, science-backed strategies, and real-world parenting support, grab your copy here:Amazon linkIf this episode resonated with you, please share it with a friend, subscribe to Mom Doc Talk, and leave a review to help more parents find these conversations.Podcast DisclaimerThe information presented in this podcast is for educational and informational purposes only.
