It's good to read this thread....
I'm dealing with my Aunt and Uncle between bad health and dementia on his part and just poor health on hers...I'm trying to get them to agree to a caregiver...not a week goes by without a problem at their house...I have had a cleaning lady coming in once a month for almost a year, and that has really helped...but...they need someone there for at least 4-6 hours a day. I have a feeling that I'm going to have to get a bit nasty and insist.
