My seven year old Son has Autism but although he is challenged by it he isn’t. severley challenged by his Autism. He is verbal but has Speech and language delays interacts well with his cousin who is two but has advanced speech and language. We don’t know what level my Son is working at as he’s school doesn’t record their devrlopmental age but my Sister said he could be working at a two year old level but slowly catch up. Could this happen?
