How old are your children?
Daughter is 16, son is 14. Both been riding since they were little - 7 or 8, but they've really started to get good the last year or so. My trainer says she can put either one of them on anything. Last time my son went to a show he won every class he entered and the Maiden Championship. My daughter placed first in all her classes, but unfortunately came up against Mom in her championship class . . . I can still ride without stirrups better than she can, and the judge got kinda creative . . . of course my horse is better behaved and has a trot you could sit forever.
