It was good for me to be able to observe how he interacted with the teacher (he far exceeded my expectations as far as paying attention and following instructions -- does he ever listen to me that well?!) and with the other kids in the class.
After seeing what it was like and being very impressed with the teacher, we went ahead and enrolled Abigail for the rest of this month as well -- although her LVAS doesn't interfere with her balance, it will be great therapy for her CP issues. And besides, she is very into prancing, twirling, jumping, etc, so she'll love it. When David's class was over, she announced, "Now Abigail's turn on that!" (i.e. the mats and equipment) She'll be pleased to have her very own class next week, and I will be sure to share pictures.
