If she is still well enough we took a holiday home in her town for a week and the family came to stay. This meant my Mum could join us for a holiday and go home to her own bed at night. The photo from this week she asked to see on her ipad the afternoon of the day she died.
If your Mum wants to be at home, get palliative care in place and a just in time box, so whoever is with her can access medical care and pain relief etc.
If there's a suitable place in her home to rest in her final days set it up. My parents dining room has a lovely view, we put an orthopaedic bed in there and that's where she spent her final days, and where she died. We had a easy chair by her bed that we used to sit for hours..her final night I stayed with her. The night before my Dad did.
Try and ask her to advise you of her passwords and investments etc and provide paperwork so you can contact them.more easily. Mum was fab and went mad at me 24 hours before she died because I forgot her phone passcide was her DOB backwards not forwards.
If there's no bathroom downstairs ask for a commode and get the liners all ready. And protective bedsheets. And silk sheet that allows you to turn her. In teh last 24 hours Mum was a dead weight and couldn't help us at all but I knew she wanted to stay home so we did manage to get her on the commode for a wee (she had a stoma for defecation).
If you know what funeral director you want gt the details and call them to warn them on death. There are doctors etc that have to be sorted to sign death off before bodies can be removed to funeral homes, but ours once they knew waited to hear and came at 10 on a Sunday night.
Love to you at this difficult time. Its awful but I felt seriously privileged to be with her as she left the world, just as she was with me when I came into it.
