Ditto everything Annie said. &nbsp;The incredible care your son is giving his grandmother is invaluable. &nbsp;Practically, it is saving your family at least $50,000 a year in nursing home costs. &nbsp;Round the clock sitters would cost nearly twice that. &nbsp;Definitely call around and find out what the cost of caring for your mom would be, and get the costs in writing from the agencies that provide care. &nbsp;The $6,000 per year they reluctantly pay your son might cover 6 weeks of your mother&#039;s care. &nbsp;To keep this from turning into an argument that rips your family apart, you will need to detach yourself emotionally from this issue enough to discuss it with your sisters from a completely financial point of view.
