I wanted to quote you, bernina, since you specifically asked but I didn't have a lot to update. We spoke to my MIL and FIL today. A new doctor came in yesterday or today and gave them a lot of hope that my MIL will walk again. He went into great detail as to what actually happened to her spine and that he expects her to have a lot more improvement in 3-4 mos. That's super encouraging!
Unfortunately, her therapy has slowed because it appears she has torn some ligaments in her shoulders with all this trying to move herself

She's having an MRI soon to assess the damage to her shoulders. She was not strong physically going into this so I can just imagine the stress on her body.
My FIL took her out of the facility by himself yesterday and they went to several retirement (55+) communities to look at houses. I think the sale of their home will not be enough to cover these types of places completely so they will have to take on a small mortgage. Not a good prospect when you are almost 70yo. They've talked of moving to FL for several years now and I honestly wish they would. I think with the large retirees there, they'd find better, and cheaper, housing options. My MIL is really attached to several of her doctors though and I think that is partially holding her back from wanting to make the change.
