Unless you have a horse who panics, humps up and kicks out towards the small child, crow hops and clamps down on the rope so hard he drags a small child along with him. Or bolts forward. That happened to a friend of mine. Its a very bad accident waiting to happen. I wouldnt wait. You just never know. My horses all know how to have a rope anywhere on their body at any time and to yield and relax to it. JMO.

Should you think that one day you may pony another horse, you can wait until then to teach your horse to stay calm. Normally if a rope goes under the horse's tail, he may squat a little or tighten his tail and it's under there for only a few strides as you stop and remove it.
