E came to play today and Anna made some good progress while she was here! At first Anna was "squeaking" to E, then she started writing notes, then for the last hour or more she just started talking normally to her. It was wonderful to witness a "normal" social experience for Anna. I think it helped to have Sarah here and not E's parents so Anna was able to relax more fully. We definitely need to get them together again soon to keep it up though!
