Elana/Faye, thank you for the feedback.
Unfortunately I agree that we aren't ready for the sit trot. Today, as she was standing tied and turned to look at something beside her, I saw the beginnings of a topline muscle along her back Yea! Been waiting a long time for the site of that little bulge.
I have a feeling that I might become lazy with a sit trot too (besides lacking the skill to do it) and she would have to lug me around like deadweight. I agree that my balance is not there yet. We have been lunging with side reins and they have really helped. Not only with topline but her balance. Her feet were like dinner plates. But since I have been asking more from her during her riding, we have dropped off from it and don't do it so much. Maybe every third or fourth time we ride for about three minutes each direction.
Unfortunately too, the foal did not make it. Long, sad story. She had him out in the dry lot and she had no milk. He lived three days. I had checked out her bloodlines, saw her on a video and when I went to see her, she was not the same horse. Previous owner led her out and said, "this is Bailey". She looked horrible (warts on her face, cut on her neck, ribs sticking out, bumps on her skin, cracked hooves and all) but I knew right then when I saw her that she was the one. I got her very cheap because she was in such bad shape. There was just something that I liked about her - ugliness and all. Can't explain it.
