My mom is in about stage six of Alzheimer's. She used to spend more time with me but is reluctant to stay anymore. My sister lives with her and is her caregiver, and she really needs a break. We sleep with my mom in fear she'll get up at night to use the restroom and may fall. She definitely needs 24hr care and we are committed to keeping her in her home. There are six siblings but only two of us caring for her. I love having her here at my house but now she gives me excuses as to why she can't stay. I want to insist but am not sure how to approach this. My mom has always been very controlling with my sister so I'm not sure if this is about the disease or always having my sister with her.
