I have an autistic friend. He has hard time communicating but he is such a wonderful person
Yes, Autism is complicaated. I am a high school teacher and my school has a program for autistic students. Their needs are so individual. 
That's wonderul! I'm glad when families get training and support as well
Yes, it's a good program that focuses on social skills and life skills. 
Parents usually notice signs in the first two or three years of their child's life
Wow, that young. I guess a baby would start to miss social milestones. 
Yes, but some kids with autism still reach their developmental milestones at a normal pace. Signs usually develop gradually
Very interesting! What a challenge to a parent. 
It is! and it's sad that there is no known cure but there have been cases of childen who recovered!
I understand it is a spectrum, ranging from moderate to severe.
