I don't have any kids, and I guess my husband would put me in a home only if there was no other possible alternative. If I needed a lot of home care, hopefully he would be able to have someone come in and assist him. If I developed Alzheimer's Disease, then perhaps a home would be the only reasonable decision. Neither of us want to be in a nursing home at all really, ever. Both of us feel that if we were very ill, we would rather opt for something like assisted suicide, rather than go to a home.
When my husband's parents became so ill, starting with his father having a major stroke that paralyzed him, we were able to move them into our home and let them have the main floor for themselves. His father was bedridden, but we were able to lift him into a wheelchair and move him around the house like that. His mother also used a walker and wheelchair at times, as she had a lot of health issues herself.
When my mother was too ill to live by herself anymore, my sister and her husband welcomed her into their home. Neither of us regret keeping our parents with us as opposed to putting them in a home, we wouldn't have had it any other way.
My friend had to put her mother in a nursing home many years ago. She said she had to visit her very frequently, just to be sure that she was being cared for and not neglected. Sometimes we would visit her mother together. It was a depressing place to be, I always felt sorry for everyone there.
