Hildy - why do you think this? I think her family has demonstrated a remarkable dedication to her.... she has a brother (unsure of other sibling?) as well as her parents.
I am speaking from experience as our family cared for my bedridden brother for 18 years - had my parents died first - I would never have dreamed of putting him in the care of strangers..... all because of the example of my parents... There is little glamor in caring for a relative in such a state - but many joys and peace from doing the right thing.....
Please don't. I've been taking care of my bedridden mother in my home for six years.
