Is your child not able to accept losing in games? Is it difficult for your child to regulate emotions when losing? This is the right book for you and your little one(s)! This book is also perfect for teachers and therapists! It's OK to Lose! is a children's book that targets a common emotional regulation and self-management issue young children usually experience when they play games! The author has uniquely applied behaviour science to children's literature, and helped young readers take the perspective of the main character in the book, explore different contingencies in their world, and learn to make good choices in different situations, in a fun and interactive way. This book was developed together with researchers, school teachers, early childhood educators, behaviour analysts, speech-language pathologists, many parents, and young children!
