Lack of Children's Yoga Teachers

I went to Kathy's house today to pick up some resources to help learn about and teach
children's yoga. Some old books, some games like Bingo, flash cards, activity books. Then we talked about the fact that YVT is not able to consistently offer yoga classes for young children. It seems that the instructor's energy fades over time. I can see how that can be, esp with children in the toddler stage. These kids just want to explore the room, the props, and themselves. It can be frustrating for an instructor who is not mentally prepared for complete chaos. It also struck me as odd that the YMCA did not have these classes, or that they were looking for someone to teach them. I reason it is for the same reason, it's hard to keep a teacher who does children's yoga.
