I will start with some flying change progress. The changes have really smoothed out. As proof, here are two HP into changes that we did at the end of the lesson this morning

He's anticipating them A LOT right now, and wants to throw them in anywhere as an answer to every aid, but at least he's (mostly) not flinging himself around or violently kicking out anymore. So I'll do one or two, for example in HP to the wall, ask for the change on the wall. And then I'll end off the ride with a HP or LY to the wall, carry on straight without the change (with some exaggerated bend and leg aids if needed), halt in the corner, big praise.
What's really really helped us with the kicking out is getting him very mobile and obedient in his neck and wither at the canter, and then doing thousands and thousands of t/c/t/c transitions all over the arena, in interesting places. He needs to go forward from the leg aid, and wait for the cue to know which leg to strike off on.
My goals for the coming two months is to work on straightness in the changes, and to start asking for more than one on the long side.
