My MIL (alzheimers) is twice my size and there is no way I can lift her if she doesn't cooperate. For the past three mornings she will sit on the edge of the bed and refuse to get up. She says "I can't and you can't make me." She sits in pee saturated depends (I put 3 on her every night) on the edge of the bed and acts like she doesn't remember that she can stand up. It requires lots of psychological tricks etc to eventually get her to stand up and this one task can last an hour or more. Once I get her up, she walks. Any advice on getting her out of bed?
