Age range: 1st through 3rd grade, or perhaps even 4th grade.
Recommended for: This book is exclusively for a child who has recently been diagnosed with OCD and is starting treatment with a therapist who is trained in Exposure and Response Prevention (ERP) . The book reassures children that they aren’t “crazy” or the only ones with OCD, and it teaches about ERP and the strategy of externalizing and talking back to OCD (the boy in this book calls his OCD thoughts “Mr. Worry”). It provides children with an analogy of medication being a child’s running shoes, the therapist being the coach, and the child being the runner (ERP is the “running strategy”). The book is a bit outdated but it’s still one of the best picture book introductions to ERP that I’ve been able to find.
