How do you help an autistic kid thrive in a nonautistic world? This book is the perfect place to start. Parents need the latest knowledge about how their child's or teen's brain is wired differently—and practical strategies to nourish their well-being. For over 20 years, this empathic resource from leading scientific experts has guided parents to understand autism spectrum disorder, obtain an accurate diagnosis, get needed school supports, problem-solve behavioral concerns, help kids navigate social interactions and friendships, and much more. The revised and updated third edition gives even more attention to building neurodiverse kids' social and emotional skills while affirming their strengths and interests and accommodating their differences. The focus is on kids and teens without significant language or cognitive disabilities. Vivid stories, checklists, tips, and resources provide a complete toolkit for helping autistic kids grow into happy and healthy adults.
