I think your niece and my great niece would get on wonderfully, Pattymac. Em has a couple of horses she does eventing with. One is a grey Irish Sport horse, and don't know but the other, looking at photo's, may be a TB. Oscar is lovely, I'm very partial to black horses. Used to love jumping them too but not competitively. I worked for one of the top show jumping guys here way back when I got bored witless and left my Bank job.
