Re: Absent Patellae
Can you enlist another adult (or older kid) to help with the classes? Even a fairly junior adult can be quite helpful in keeping the teacher from being spread so thin.
I was an assistant coach in our kids' classes from a point where, frankly, my aikido was about on a level with theirs. But I could sit in the line with them and keep them from poking each other, let them yank my arm while learning pins so that they weren't yanking each others', etc.
