My sister and her husband are on holiday at the moment, so I am "housesitting", but really here to pop round to Mum's every day, and do some jobs for her, like my sister does. Basically, to make sure she's eating.
It's a tough time, as Mum wants to stay in her house, but she's got two types of dementia, and has deteriorated quite a bit since I last saw her. I expect that the inevitable will come, but she's also started throwing, "if I'm still here" into conversation, why she's having lucid times.
Mum isn't the easiest person to help.
