Good for her for being a brave girl. But I'm with the others. She is tiny and doesn't have the weight or strength to save herself. She was lucky this time. I see the same thing every week at my barn. I really have to bite my tongue a lot. The best kid rider at the barn is a disaster waiting to happen. Has no actual ability, just kick/smack and go. I have seen her go over jumps and my heart can't take it. A good dressage coach is needed. Teach her to use her body and give her time to grow.
