Hello guys! Thanks so much for the feedback. I have had my baby and will be able to ride Tia again soon. This means that flat work will be worked on more than jumping, both because I just had a baby and because I just took 9 months off of riding and I will need to rebuild muscles. So I agree with the comments on the rider, and I will be back on my own horse soon enough. I also agree with stopping after jumps, so if...when I'm finally ready to jump again, Tia still rushes her fences (both before and after) I will try the stopping after jumps. But hopefully all the flat work needed in order to get me back into shape will help her learn.
I personally have had better luck with flat work and calming down before the next fence than I did with stopping after the fence. I tried that (stopping after the fence) for a long time with my TB and it never worked in the long run. The other method worked much better. Good luck!
