★The much-anticipated new work from the rising Korean picture book author, Hyun-young Lee! A children’s picture book about losing baby teeth!

★Gently guiding children to grow up with confidence:
This book, with its warm stories and vivid illustrations, helps children face the challenges of growing up with a positive attitude. Hyun-young Lee, with her unique artistic style, transforms the natural process of losing baby teeth into a milestone for children’s confident growth. Suitable for parents to read with their children, celebrating every moment of growth together.

Around the age of six, many children begin to lose their baby teeth as their adult teeth start to grow in. For some, this can be a scary experience—they worry about pain, not being able to eat their favorite foods, or feeling embarrassed in front of friends.

This heartwarming picture book reimagines that moment as a milestone: the day you lose your first tooth is the day you start becoming a “big kid.” By turning fear and uncertainty into pride and growth, the story gently encourages children to see change as a step toward growing up with confidence.
