One thing we've always done with em is "show" her her feelings (suggested by her AT). Since she doesn't feel her feelings or always connect them to what's on her face, we show her in a mirror and help her connect them. (I should explain that better, but it's late and I'm lazy).
In the car, she was really annoyed with me (because I touched her at the same time she thought she was "in trouble" so she was all tense and weird - and then I pointed that out). But she was making this very annoyed/frustrated face and I said wow are you annoyed with me for pointing out your feelings, look! And I took a picture of her. When I showed it to her, I expected her to just continue being annoyed, but she grabbed it and said WOW, do I seriously look like that?!
It cracked me up. Definitely not her best look. :)
