Thank you MON for the advice. I appreciate you taking the time to help.
ETA: I don't think she's been treated poorly or bullied. Although the one girl who started playing with her good friend is pretty bossy and pushy and while I don't think she's directly bullying dd I can see how she makes dd uncomfortable and not included. Sort of a manipulation type scenario.... hard to explain.
Otherwise dd has never been bullied that I know of. The kids always seem to speak very highly of her. She just doesn't seem to fit in or know how to.

She's just different.
