God bless my sister and my stepbrother and my other stepbrother's wife!!!
They have made arrangements, and I will not have to boogie down to Phoenix after all. Oldest stepbrother will be there Monday, and he is going to get his mother to stop dithering and refuse POA for Daddy (along with executor & other things). She has been her normal "oh, someone please tell me what to do" self, and her oldest son is just about the only one she will listen to. Step-SIL also arranged for a couple of extra caretakers (brings the number up to four total); two that are there 12 to 12, one am & one pm, and two that will be part-time during the day. One care-giver during the daytime cannot care for two infirm or bedridden patients in an in-home setting. They both need so much attention that there would be no time for cooking meals or bathing one or the other, no way to run errands, get groceries, or take them to their millions of doctor appointments (they average 3 a week between the two of them).
