Haha I feel your pain!! I am 5'0 and my boy is 15.2 & 1/2 hands.. I can't even see over his back! I have tried for years to jump on a horse, and I have completely given up, lol. My legs are so short, there is no way I could ever make it up there. I use an old mineral lick tub as a mounting block..

Works just fine. Out on the trail, I try my hardest not to come off. The closest I've come was when my mare stopped when we were loping. I'm talking her brakes locked up and her head went down. The only part of my body that was still over her back was my left foot, and I was barefoot in the middle of a sticker patch.

Don't know how I did it, but I managed to pull myself up with just my foot. Pulled the calf muscle, but I did it!

Moral of the story: hang on and don't let go!! Lolol - Good luck!
