Your son sounds like he has some typical 2 year old behavior. I'm not saying he doesn't have RAD. I've no experience with RAD. But I have had 8 children and some of them became VERY antisocial from about 19 months to 3 years. They finally pulled out of it and are wonderful kids. They were just strong willed. I have also had very sweet 2 year olds.I was with a 2 1/2 year old for a week the other day and she would let me do things for her but not her mother. She had a sweet smile for me and anger toward her mother.I am sure she will get over it.
