My family took care of my grandparents when they were old. Everybody took turns and watch them. So I can not talk, based on my experience.
I have a coworker who had to put her mom in a retirement home. She was sad because she did not want her mom there, but her mom was losing her mind and needed to be in a retirement home. My coworker looked for a retirement that was close to her house and that allowed family members to visit anytime during the day.
She would visit her mom in the morning before work. She will also visit her right after work, in the afternoon. The visits were short, but she was able to see her mom and talk to her everyday.
This was important to her. At the same time she was taking care of her husband and kids. I never heard she had any problems with the retirement home.
Her mother died two years later.
If you are home, have a reliable income that doesn't require you leave the house to work, and are emotionally and physically able to do so - your home might be the best place for her. It can be very rewarding to care for your loved ones but it is also demanding, difficult work. And, it has been my observation that your siblings are likely to think you are doing it all wrong.
If you HAVE to work outside the home and do not have a strong support system, then you are kidding yourself if you think your parent will be safe because you cross your fingers every time you go to work for a few hours and leave the phone within reach. You can hire aides and sitters,adult daycare, but in the US, that is private pay (not insurance). Even home health is approximately an hour a few days a week, depending upon the services your parent qualifies for (IF she does).
Then there are those who could stay home and not experience an economic tailspin - they don't HAVE TO work, but do because it is a career, part of their identity. If this describes you, then you have to weigh your parent's need against your need to maintain this career, achieve your own goals. If a nursing home is the most appropriate option, it doesn't mean you will never see her again.
You have some options in selecting a home. If you wait until the last minute (ready to discharge from a hospital) and the parent has Medicare (including supplements and replacements), your parent is going to have to go to first available in the area, but you can place her on waiting lists in preferred facilities. You can visit often - daily, weekly, make drop in visits to check care across the different shifts.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
