Elderly Mother and her husband are the guardians of my neice and nephew. The kids are 9 and 13. Mom was diagnosed with dementia last week. Her husband has a history of heart disease, has had some stents, has back pain, smokes a pack a day and has type 2 diabetes. He does not walk much and sometimes falls back into his chair when getting up. Both Mom and her husband are very private. I am worried about their safety and the kids. Any thoughts?
