In this imaginative, authentic book, four-year-old Elias depicts his experiences growing up in a neurodiverse family, with his autistic Mummy and brother and non-autistic Daddy. Using bright and colourful drawings, Elias thinks about what it means to have different kinds of brains and shares his encounters of the differences between his parents on a day-to-day basis. Elias’s story is accompanied by his Mummy Joanna’s commentary, where she explores parenting across the neurodivide and how we can promote understanding of difference. Key features include: A foreword by neurodiversity advocate, author and former teacher, Chris Bonnello A unique exploration of the Double Empathy Problem, emphasising that the difficulty is difference without understanding, not the type of brain Bright, engaging pictures perfect for inspiring conversations about neurodiversity and family dynamics between people of all ages An insight into different neurotypes and how understanding changes with knowledge, as perceived by a young child Accompanying explanatory text that expands on themes in the story My Daddy is Not Autistic (But My Mummy is) provides a unique perspective on growing up in a neurodiverse household and is a valuable, often humorous and joyful resource for all people seeking to explain and understand difference, regardless of age.
