Here's what the video discription says:
"To all that have commented about the helmet. Sianna is required to wear a helmet every time she rides. She was riding Lady right before we did this video and I missed it that she took the helmet off. It was super hot and she must have set the helmet by the gate."
You "missed" that your THREE year old took off her helmet before lunging then riding a very large horse bareback? All while filming her for almost 5 minutes?
