My wife an I live in our small house with my MIL (89). She is not infirm but very needy. We can afford an hourly caregiver but we are concerned about how we could best use her services. My wife is at home now being between jobs and I work out of my home office. My MIL is very dependent on my wife and we are trying to introduce the caregiver to allow my wife to be able to leave the house for longer and periods of time or even go out of town on vacation. My MIL refused to go into independent living. She complains about being lonely but refuses to join any activity. She depends on my wife to entertain her.
We have no relatives to help us.
This is what worked for me when my Mother lived with me: I got her up in the morning, had a nice breakfast with her, got her showered and dressed, then the caregiver would arrive. I had usually been up several times in the night with her, so by 10 am I was ready for some time to myself.
Sometimes I would work in my office, some days I just cried from exhaustion, sometimes I would leave the house. It is not the same as really being free, but at least it relieves one for a few precious hours of the annoying neediness. We had another caregiver who would take Mother out of the house on a daily excursion to the beach or park, or one of the senior centers so that I could be in my own home in peace for a few hours, cleaning or doing yard work. Oh yea, cleaning my house was my idea of a vacation when she lived here. Obviously, I am not your best example of a selfless, doting caregiver, but I'm sure you will get answers from them, too.
I gave my Mother very good care, but did not take care of myself very well, and caregivers must be healthy and rested. Put your Own oxygen mask on first.
I visit her several times a week and do a lot of things for her in the care home where she is on hospice. Encourage your wife to save herself NOW. Bless you, good husband.
