Sianna Cessna 3 year old girl riding 16. 3 hand horse

Short vidoe of my 3 year old daughter Sianna riding Cessna a 6 year old Thoroughbred, Draft Cross mare. She is 16. 3 hands. Cessna is my husband s horse, but this summer Sianna s horse came up lame (not Lady) and we had to does awesome with Cessna and even though we have Lady back Sianna has continued to ride Cessna. They are now riding in the big arena with out any assistance at all. To all that have commented about the helmet. Sianna is required to wear a helmet every time she rides.
