We still differ.DL, Nan sounds like just what you need, I hope she works out well for you. I think you have been very clear-eyed and level headed about your DH's condition, so please don't get me wrong, but I was a bit concerned that you and his family seemed to be seeing things differently about his need for a caregiver. I just know that a lot of families only realize that their loved one has reached the point where they aren't safe on their own after something unfortunate has happened. I'm sure it will be a huge load off your mind to know that he's not alone when you can't be there.
I think he needs some help during my absence but doesn't need to be accompanied at all times.
I'll continue to evaluate his abilities daily as I've been for years. That is why little by little I've been taking over all major aspects of running the household. He just can't do things that require much thought and foresight any longer.
When I get the first inclination of a real safety concern, he will have to have full time observation. I'll cross that bridge when I get to it.
