Good morning, @alive Your post brought back many memories for me. I am sure others have far more positive experiences or live in areas with more services available, but this is what I found.
All I can add as an answer to your question is with us it took a whale of a lot of trial and error, finding good resources, then having them disappear or go out of the business. I discovered finding caring services was just as challenging as finding a handiman, a good plumber, or a dedicated PC doc. A significant challenge for us was finding individuals who actually wanted to do in-home care work. Some were personality problems, two actually burgled our house, one tried to convenience my wife to write me out of our wills and name her, and one was so verbally abusive I got a call from our local coffee shop while I was out of town to tell me. So a ton of trial and error. We found this to be true with every for-profit home care company as many employed folks without the necessary knowledge. Also as my wife's needs increased, some helpers would refuse to continue working with her.
All that said, once my wife was prescribed home hospice care, we found excellent folks!
I congratulate you on thinking about this all in advance.
Strength, Courage, & Peace
Wow! That sounds like a nightmare! That’s also my fear. It’s sad that there are so few good options for in home care as we age.
