I have in fact at times wondered if AC (who is the closest this system has to a child self) "counts" as a child-self because she doesn't do the overt age markers. (She rarely fronts strongly; when she does the voice differences are noticeable, and some of the diction. That's about it.)

I don't think she cares much about being identified as a kid in the first place, though. She is who she is. (She gets a real kick out of playing with our niece, though.)
