I just finished up floor time with Guido. This is the first day he hasn't hidden in his pigaloo the whole time. He didn't run all over and play, but darted from place to place and even came out and explored. I use my old PC room for floor time, it's really working out well. There aren't and spots where I can't easily get to him. I can close it off, and leave the room if need be. Progress on every front with him.
I really do think he'd do better with a friend, but just because I want one there doesn't seem to be the right one around.
