Re: Last stage ??
Does your mother have Alzheimers? if so, the symptoms you describe may be the final stage. In her last few months my mother could not swallow, lost interest in food, slept a lot.
Mom was at a nursing home and there were no fights over feeding tubes. She had a ''do not resuscitate order" made out years before. They knew they were not allowed to force feed her or feed intravenously. They had Hospice come in to make her as comfortable as possible, and she passed away peacefully. She needed round the clock care by than and it was good that we had her in a NH. I had gone to live with her, and stayed there 5 years. It is a hard path you have chosen.
I hope all goes well for you in these final months.
