It can definitely feel overwhelming when you're first navigating an autism diagnosis. A book I found incredibly helpful is "The Reason I Jump" by Naoki Higashida—it provides a unique perspective and can really deepen understanding. Websites like Autism Speaks or the Autism Society also offer a wealth of information. When it comes to communicating with teachers and healthcare providers, creating a shared document with your child's progress, needs, and any interventions can facilitate more effective communication. It's also beneficial to ask for regular meetings or check-ins to stay updated on your child's development. Remember, you’re not alone, and seeking support groups, either online or locally, can provide community and encouragement.
