I am the mother a very beautiful boy who also is high functioning autistic. Autistic children for those of you that do not know, do not like to make eye contact or look when spoken to. My child as as infant expression was always serious, frowning, and distrusting. So I had to create ways to capture a smile, but I also learned to capture his true expressions with yelling "look at me" or "Smile". Ok, so you see where I am going with this? I will chase, tickle, talk Disney characters or do whatever makes your children happy to capture their true personalities and their best expressions. I even had Jellybeans thrown at me in fun and what an adorable image it made.
