My parents, both teachers, saved all their lives so they could be comfortable in their old age. There was certainly no expectation from them when they were younger that I would be expected to take care of them. I can remember my mum saying to me that when she was unable to look after herself she would like to have someone look after in her own home rather than going into care home, and she certainly meant a paid person not me.
Roll on mum's dementia starting around 6 years ago. Mum was in denial, wouldn't admit to there being anything wrong, telling me she cleaned the house and cooked daily. Dad looked after her until it was apparent that due to his failing health he was unable to manage so I had to step in and assist with the cooking, cleaning, shopping, taking them out etc. I did it because my mum wouldn't accept in paid helpers and dad wouldn't do anything outside of her wishes, and I would let my parents be in a situation where they weren't eating properly in a dirty house. As I worked part time it was manageable if not ideal until we came to the point where additional personal care was needed and mum just wasn't safe.
After a difficult couple of years my parents moved into a care home and although I'm pleased I was able to support them being at home as long as possible, I think it would have been better for both of them if they had moved sooner.
I have a friend who lives with her widowed mother who had promised her that she will not let her go into a home, she has no life and is in the process of giving up her job now her mum needs someone with her full time. I have said to her that a nice care home can be the best place for someone but she has said that it's not for her.
My DS has already told me that he couldn't do for me what he watched me do for my parents - but he'll find me a nice care home!
I hope that DH and I will have the self awareness to take steps to make our lives properly manageable in our end years before it's too late to make the changes ourselves and it becomes
crisis point which is what I think happens in most cases.
