Part of being an instructor is knowing when your students are ready to do more challenging tasks. That's part art and part experience. We know if we wait too long to allow our students to jump, they may get bored and go somewhere else. If we let them jump too soon, they may get hurt and you get sued.
Here, IMHO, is too soon. I am not picking on the kids. They are very cute. I am not picking on the useful and saintly horses. They are also cute. I am simply showing an example of "too soon" and if you go to court with a hurt student and this video bring your checkbook. The camera person is out from lessons with a broken arm.
Too soon? Just fine?
