I have five sisters between the ages of 46 and 66. Both parents are 87, Dad has dementia, Mom isn't far behind. Mom insists on staying at the home although there is no bathroom on the first floor and they have to go up the stairs to go to the bathroom or bed. They now require 24 hour a day care. The sister who is staying with them during the week is draining their finances and Mom will not stop her. There are only three of us who are able to stay on the weekend, but this has been going on for well over a year. They are truly no safe at home even though we have made major adjustments to the house. When is it ok to throw in the towel and tell them that they need to go into the nursing home?
