I've worked with over 1,000 kids: How to say 'no' or 'stop'—and actually get them to listen

Saying “no” is essential in parenting. But setting limits shouldn’t start and end with that one word.

As a certified child life specialist and licensed therapist, I know that saying “no” is meant to help kids feel safe, supported, and understood. I often help kids understand: “Your parents aren’t saying ‘no’ to control you, they’re saying ‘no’ to support you.”

Boundaries deepen trust and cooperation over time. When we say “no” with calm, consistency, and care, we’re setting limits. But we’re also teaching emotion regulation, self-control, and connection. These are crucial skills our kids will carry far beyond childhood.

Here’s how to say no in ways that build connection instead of conflict.

Think about a curious one-year-old who’s putting sand in their mouth, pulling the dog’s tail, or standing on a chair. If we just say “no” or “stop” without explaining, we might leave them feeling confusion, shame, or doubt.
