Lying, Backtalk, and Saying ‘No’: Why It Happens—and How to Respond

Why is your preschooler suddenly telling tall tales, refusing your requests, or arguing back at every turn? Are they testing boundaries—or testing you?

In this episode of The Scientific Parenting Diary, we unpack five of the most common “problem behaviors” in children ages 3–6: lying, backtalk, constant defiance, fantasy-driven statements, and mimicking inappropriate adult language.

But instead of labeling these as disrespect or disobedience, we explore what developmental psychology has to say. You’ll learn why these behaviors often signal cognitive milestones—like emerging self-awareness, imagination, and even early moral reasoning.

We also share practical, science-backed strategies for how to respond—with empathy, structure, and intention—so you can guide your child’s growth without power struggles or punishment.

Whether you’re feeling frustrated, confused, or just curious—this episode will help you see your child’s behavior in a whole new light.
