My father-in-law has dementia. He’s 89 years old and is bedridden— he can only get out of bed with help. He has caregivers during the day and evening. When they leave at night, they lock up the house. My worry is what could happen in case of a fire since he can't get up and get out. I think he needs to be put in a home where he can get 24-hour care. He could have that at home, but refuses for anyone to be in the house at night. We can’t make him understand that he needs someone there all the time for his safety. He has money, but he says he can't afford it. When we show him that he can afford it, he agrees, then changes his mind. What can we do? Can we be held responsible for his safety?
