If you want a calm, non-preachy way to introduce the concept of gender identity to a preschooler, Introducing Teddy gets the job done cleanly. Author Jessica Walton keeps the focus on basic kindness: when Errol's teddy bear reveals she is actually a girl named Tilly, Errol's main concern is simply that his friend isn't sad anymore.

Instead of bogging the story down in heavy explanations, the book uses everyday pretend play to show how listening to a friend builds trust. It is short, direct, and comforting for early listeners.
