When I was my mom’s caregiver in my home this very issue is what led, eventually, to moving her to an assisted living facility. For several months I would waken in the middle of the night to see my mom standing at the foot of my bed. When I had to leave for a short time I came home one night to see her standing at the stove trying to figure out how to turn it on. Her safety (and mine) were really at risk and I could not provide the 24/7 oversight plus the supervised entry/exit a facility would offer. Truly the hardest decision I ever had to make. I felt like a failure but at the same time recognized that I would NEVER be able to provide her the supervision she needed going forward. Once she settled into the facility I was able to spend meaningful times visiting knowing she was safe. Hard times for sure.
