Also, where I grew up most people started riding their horses at 2 years old. I usually prefer not to start them until they're three. However, the examples around me are starting to get to me... THEIR horses seem fine... My horse is a QH/Mustang, so he shouldn't develop way late like some... I only weigh 110 pounds... surely simple walk/trot/canter and trail rides wouldn't hurt a two year old, they do all that in the pasture! What do you guys think? Should I start light riding as a two year old, or stick to what I normally do and wait?
