Wow. When I was a kid I never dreamed of having a pony. Luckily, when I grew up, I could afford to pay for a horseback riding course. I've been doing it for a couple of years now and I'm very happy. To you, as parents, I can recommend this
Horse Riding Blog. I don't know what age your child is, maybe she's old enough to read this blog on her own and learn equestrian theory. Best of luck to her!
