Holy moly!!! I would be telling your friend to find a new MCHN cause this one has no idea what she is on about. I was going to say the same thing as megie and that it would be due to her slight prematurity as opposed to anything else. I know in some babies the *signs* of autism can be there from the start, but not smiling yet at her age isn't reason enough on it's own for her to make such an ill-informed judgement about her.
