My grandmother, who is 91 years old, currently resides in a care facility. My mother anticipates my visits every other day, and on the days when she can't make it, I'm expected to fill in, which occasionally results in two consecutive days of visits or more. It's been several months since my grandmother moved into the care home, and I'm attempting to convey to my mother that maintaining such a rigid schedule might not be sustainable. We should have the flexibility to visit when we can, without adhering to such a strict routine. My Mum doesn't take this well and gets very short with me and angry. I don't really know what to think.
