Oh, Choux, your dear mother's diary entry has made me very teary. What a compassionate and clear-sighted woman!
At one point my DSis and I managed to persuade our DM, who is the one with POA for our DF, to sit down with us and the nursing home manager to work through some kind of care plan for our DF. DM was very reluctant to engage with this, and to be honest just went along with it to shut us up and has since ignored it completely.
But it did give an opportunity to discuss various aspects of care and treatment, and that could be helpful for you. We've never met with the GP who works with the nursing home, and it would have been good to have had their input as well, especially around the giving of medication for comfort v medication for treatment. Given you do have POA I think you should be able to specify that you should be consulted about any medication, and you can give them a strong steer towards minimal intervention.
I have really struggled with the approach to feeding my DF. He has been getting spoon-fed mush for about a year now. He can hold a cup to drink. At one point last year he was extremely thin - BMI of 15 - and so the nursing home and my DM were at great pains to get as many calories into him as possible. So they were giving him very calorie dense foods and drinks. I suggested that he simply be offered or given the usual food, and basically let him fade away, but my DM's response to this was that she didn't want him to be starved. I wasn't suggesting that - simply that I didn't see the point of feeding him up so he can be miserable for longer. I find it all very distressing, and I think I posted about it here at the time. It's made worse by the fact that my DS was a low birth weight baby who was tube-fed, refused the breast and was very difficult to wean onto solids. There seems to be more support and care given to feeding a man at the end of his life than there was to my son at the beginning of his. But I digress.
Every so often, when my DM tells me about antibiotics, or vaccines or how much food she managed to shovel into him, I say "to what end?"
Is the purpose of this (whatever this is) to make my DF more comfortable or is it to prolong his existence?
Once a week I take my DM to visit the nursing home, and I spend my afternoon eating biscuits! So I also appreciate the chocolate biscuits on this thread!
