I forgot to put my stirrups up after I was warming him up, and didn't notice until you pointed it out! I'll try not to forget next time :P
Thanks for putting everything into really good detail, and describing ways to fix them.
I'll try to get a photo/video of us jumping higher, but I don't want to go above 70cm until I know that he is fit enough to do it.
Again, you've been really helpful (:
