I have observed how they do things in my husbands culture with regards to parental care.
Firstly, I believe this is why they have a lot of children. To spread the burden.
My grandmother inlaw went partially blind from diabetes but was mobile she would spend 3 months in each child's house being looked after. All of the other siblings would help going to whoever house is was.
It didn't look too strenuous, most people had children and she would become another fixture in the home. The adults also seemed to be in competition trying to be the best host, having parties etc it never seemed depressing. By the end of the 3 months though you could tell the host was fed up but then she would move on. (I knew this from my mum in laws turn)
This would even take her across different countries as a lot of her children lived abroad.
This is in a culture where care homes don't exist so I'm guessing its not a choice its just something they are expected to take on.
When it got too bad and she became immobile she spend most of the time at her home with a paid for carer but then all of her children would take turns staying with her and keeping her company and taking her out.
I like to think that I would do that for my mum but my mum only had 3 children and what if she has complex care needs?
Is there a hybrid system of care, where you can have a carer part time if needed?
I also think about myself, what do I want when I'm older? Will I burden my children ?
My own grandmother was looked after heavily by my mum whilst my auntie didn't really do anything. It seemed like she needed a lot of care and me and my sisters would often take her to appointments etc.
After a while she moved into a care home and was 'out of the way'. I would visit her but not often and shamefully it was because it was boring and depressing.
