Benjamin started out not wanting to go at all because I had showed him a video online of the class, and he did not want to "have feet" (bare feet). He also didn't want to wear shorts. We didn't push the issue. Once we got there, the teacher encouraged him to go try it out, but he hung back and told her, "I don't NEED to go play!" So he stayed on the sidelines with Frédéric, sneaking glances at the other kids. Finally he decided he would go try it out, and he hasn't looked back. He still won't agree to shorts, but he agreed to "sports pants" and bare feet. It's progress.
So we went again this week, and today they learned how to do a somersault.
Well... sort of.
