Thanks for the input and kind thoughts all.
Given that MIL doesn’t know her daughters’ names or the day of the week, I seriously question the extent to which one ought to rely upon her most recent utterings.
Personally, I’d probably advocate anaesthetizing half the people in my MIL’s facility. But - of course - that is impossible. More realistically, everyone has to decide where they stand on an extremely finely graduated continuum. SIL does not want morphine b/c her opinion/impression is that every old person she heard of getting morphine died soon after. She fears it will hasten the end. Based on 50+ years of knowing her, my wife knows that any effort to discuss with SIL will be interpreted poorly.
SIL also doesn’t believe MIL is in pain. I suspect MIL may be putting on best face for SIL, or simply incapable of accurately expressing her perceptions. When my wife held a cup for her to drink, MIL said the straw hurt her tongue. When she reached through the bars to pet my dog’s head, she said he hurt her - even though he didn’t move. The facility staff and hospice workers advise morphine. But SIL knows better.
Meanwhile, MIL is on various maintenance meds - which she really oughtn’t be on if she is on hospice. Like I said, SIL is not fully committed to hospice - I don’t think she acknowledges that he mother is actually approaching the final stages of dying. MIL is also on O2.
Realistically, I would stop any efforts to make MIL eat - maybe bring a healthy shake and offer it when she was awake. Or maybe just bring it if asked. I’d stop all maintenance meds other than palliative, and would probably discontinue the O2. But my opinion means nothing.
Having an old relative in this situation is taking a toll on my wife’s emotions. Just a nasty cloud to have hanging around you all the time.
I wish the government or medical community required end of life sessions - maybe every decade of a person’s adult life. Show real-life films of people at various stages of decrepitude, and ask which existence one prefers. Give interviews with caregivers and family members - including ones who find some value in wiping their parents’ asses. Identify potential caregivers in the family and ask how they feel about taking on what roles. A person’s expression of their preference would be afforded less weight as they lose mental competence. I really wonder how many folk would wish to continue existing in the state my MIL is if they knew ahead of time what it was really like. Instead, seemingly reasonable incremental decisions get made along the line, leading to IMO horrible long-lasting situations.
Final thing to give full context - their family was never terribly close. MIL was an alcoholic - never a loving, supportive mother/grandmother. SIL is a control freak who still feels she ought to tell my wife what to do as the older sister, even tho both are in the 50s. My impression is that SIL is attempting to re-write history and create a caring dynamic that never existed before. My wife - a lawyer - was the power of attorney and executor until some time a decade or 2 ago when it was changed. We have no idea of the exact dynamics of why it was done or at whose urging. MIL has always been very malleable, and MIL and SIL have always been closer than my wife was to her mother. Fine - SIL has the authority. She can make what decisions she wishes. But if she knows she is making decisions my wife disagrees with, she ought not continually ask my wife’s “blessing” of those decisions.
