Really frustrating since I have kids 2 and 4 just trying to do the best to raise them and have fun when they are little ones but damned if my folks priorities don't get in our way.
You reminded me of my last caregiving episode that I neglected to mention in post #2.
My daughter had just turned 3 a couple of weeks before my grandfather died in 1998. My son was 7 months old. That night, my grandmother was in shock and a big mistake was made, IMO. Her son and DIL immediately told her that she would be living with them from now on. They whisked her away from the house, my childhood home, almost as soon as my grandfather had been whisked away in a body bag, from what I was told. No time for her to think or process anything. I only learned of everything the next morning.
Immediately the conflicts started between them. After hearing of the squabbles for several weeks and relating them to my husband, he suggested that we give them all a break and have grandma come to stay with us on the weekends. My grandparents, besides raising me (because of said mother's condition per post #2), had been an integral part of my kids' lives since birth. It seemed like a win-win!
Nope. Over the next few years, the squabbles between her and her son/DIL continued and escalated to the point that she was spending more time at our house than theirs. She started becoming hostile with me. She was continually angry and complaining. She lost interest in the kids. I was concerned about her behavior, especially in front of them. Having her was becoming unbearable. This was not any way I'd ever expected to feel about her. She became a totally different person from the woman I'd always known. I'll leave out other complicated details, but...
Fast forward to a heart attack, a trip to the hospital, and the next thing I knew, I was charged by the hospital staff with picking out a nursing home for her with less than a day's notice! I got the call in the afternoon and they wanted to discharge her to a nursing home the next morning! Somehow, I did it, with my 4 year old underfoot.
She was greeted by the nursing home staff so warmly when she arrived. Within a few weeks, there was a definite chill when the staff came into her room. She'd been becoming as difficult, angry, hostile, with them as she'd been with us. After she was in the nursing home for a few months, they said she had dementia. That explained her personality change.
Sadly, eventually, I had to walk away. Yes, I felt guilty. I had to bring my son with me on the visits and her unrelenting hostility towards me was evident. This was not the woman who'd lovingly sacrificed to raise me. She'd become a stranger. Ironically, when she was dragged into becoming caregiver to her mother so many decades earlier, she'd said how fortunate it was that her mother hadn't become an angry or violent person, because sometimes that happens. If she could have foreseen it would happen to her decades later, she would have been appalled.
