A picture book about self-confidence and setting boundaries for children aged 4 and up, which empowers kids and conveys an important message: You can learn to say no! Cheerfully, the little mouse strolls across the field when suddenly the fox appears in front of her. With a nasty grin, he looks at her curiously and engages her in conversation with feigned friendliness. The little mouse trembles all over, as it is clear that the fox has bad intentions. But luckily, you don’t have to say that you are scared. "No," the little mouse keeps saying, no matter what the fox asks or says. Because "no" means "no," and she knows that well, and it applies to nasty foxes too! An important book with expressive illustrations by Hildegard Müller and tips for children from Dr. Lars Burghardt, Chair of Early Childhood and Family Education.
