School time was a go. I told Becca we were going to play a game called Becca says, where she gets to pick a person in our family and have them perform an activity. I showed Becca a picture of each member of our family, then attached all five to the left (her left) side of the plastic communication board. I let her look over them and she looked around at all the pictures in a circle a couple times, then back at me. Then I showed her three pictures, one of a person dancing, one of a person singing, and one of a person jumping. She would look at the picture and then look at me, and I'd say what each of those pictures meant. Then I attached all three actions to the right side of the board.
Then I explained again that we were going to take turns picking a person, and then picking an action for them to do. I asked her to first pick a person and she looked quickly and for a long time at mommy. Then I suggested she pick an activity for mom to do. Her eyes would dart quickly back and forth between the people and the activities, and I wouldn't count it unless she sustained gaze, but she darted back and forth quickly a lot for this activity ("Mommy jump daddy sing brother sing sister dance" in like three seconds). After some prompting she looked long at the "jump" picture so I called out to mommy and asked if she would come jump for us. She came over and jumped up and down. Becca got a big smile on her face.
We took turns letting Becca and her sister pick (and her brother occasionally when he was interested). Becca chose difference people and different actions clearly. She would spend extra time looking at the people side, and sometimes it seemed like she wanted to change her person choice, but I wouldn't let her, I'd tell her that we'd already chosen a person and now we needed to pick an activity. After some more prompting she would pick an activity.
After the first time Becca chose to have her brother sing a song (which he did, with a lot of help), daddy dance, Becca sing a song (we sang one together), mommy jump again, brother dance, mommy sing a song, and maybe a couple other choices. Becca's sister would also choose some, though the only one I need to bring up is when she had daddy jump. Becca got a really big smile on her face and the next time it was her turn she had daddy jump again. One time in there I also picked and had Becca dance, and we danced together. She liked that, but she didn't like "jumping" in her chair when her sister picked that, it stressed her out a little bit.
