Errol and his teddy bear, Thomas, are best friends. They do everything together. But then Errol notices that Thomas is sad. Thomas explains that she has always been a girl teddy, not a boy teddy, and Thomas wants her name to be Tilly. Errol loves his friend unconditionally and doesn’t care if his teddy is a boy or a girl. This book is a great way to talk about transgender people and the importance of loving and accepting them when they tell us their truth.
