The last couple of days have had some improvement! Terry sat up yesterday almost all morning! He had his breakfast and watched some tv and dozed :) while in his chair. The last time he was out of bed was Monday, so that was a biggy! This morning he's been talking and cheerful. We've been up since around 6am. He's sleeping again. I'm going in to bathe him after he rests some, and try to get him up again.
As I type this it seems a little silly, but in our life right now every small action on his part is major. So, hopefully this doesn't get too boring.
