We know what the next question is, and no, we don't know about surgery yet. We're just enjoying this huge step in the right direction and we'll get to surgery eventually. The great thing about the progress he's made is that they will have "wiggle room" to give him lots of support after surgery when he's really sick again.
Although we want to dance in the hallways, we're trying to remain cautiously optimistic because he still has so many more hurdles to jump, but we're so thankful for the progress he's made today.
Because he joined the cool kids off the jet vent, he got a new pair of cool shades!
Notice the jet vent turned off in the center of the pic :)
