It seems that you are not seeing any problematic social skills.  Trust me, if they are truly impaired (again beyond personality traits), you will know.  I haven't mentioned this earlier, but anxiety can seriously inhibit a child 's (or anyone's) social skills or give a false impression.  Sometimes I see kids who act really odd or "goofy" in their early sessions,  and it came down to their nervousness.  Examples:  one child who wanted to spell his answers to my questions,  another who talked the entire time with a pillow covering his face,  and lots who laugh and get really "silly".
Your counseling psych will be able to give you a clearer impression of any concerns socially, as dd has (or will have) a relationship there.
