Progress: he moves forwards, softly, when slightly uncomfortable

I wiggled the pad towards his hindquarters, and he moved his feet forwards. If I get this on both sides, I'm happy. For now, asking him to stand still, and be tense, would be unproductive. Standing still is great, and we'll get there. Right now, I would rather he moves forwards and not over me, but stay with me, bending. 

I have made small approaches to make sure he doesn't get surprised if something changes sides over his back and trough his blind spot all along. Here, he's already a bit "up" because of the raincoat on the chair nearby. He's jumpy about the saddle pad appearing on the off-side, and almost jumped on top of me. Had someone just carelessly thrown a pad on him, he would have gotten more troubled -- and perhaps even gotten to expect trouble and not be so trusting the next time around.

Because of these small steps from day one, and because I was aware this might happen, it was no biggie, just another step towards preparing to saddle & get on. I got to release for forwards movement.
