Thanks, gacl, for your kind wishes for my mom's recovery. She's doing very well still, and is expected to make a full recovery.
We got some good news over the weekend. My mom agreed to have a nurse stay with her for half days (she doesn't really trust doctors or nurses - I've never really known why not, and there could be a lot of reasons). Anyway, this means that there can be somebody with her five days a week, and my siblings and I will use less of our vacation time, be under less stress, etc., which is good.
Thanks again for all your support, everyone.
Tom
