You were right to find some help for her. But please know that your sister is right too; it's not that she doesn't want to take care of your Mom -- it's just very time consuming and difficult especially when you are trying to take care of your own life stuff. My siblings all live about
2 1/2 hours away, so I'm left to care for both of my ailing parents (Mom has Alzheimer's) and at this point, I have no sick time left because I've been running to help them. The whole family agreed when my Dad broke the femur in his arm last year to find 24 hour care rather than place him in a skilled facility. THat's when we found out my Mom's memory was failing. I've had this service now for over a year and at a minute's notice they have been able to adjust hours to meet my parent's needs. Now they are down to 8 hours every day so someone can bathe my Mom and feed my parents, grocery shop, etc. I'm there as much as I can be, but I do hold down a full time job, and have a family to take care of as well. Plus my job requires travel. And I take care of paying their bills too! Try to work out things as a family and it will be better for your Mother. My husband is back on the east coast right now trying to do the same thing. Work together...it makes life much easier for everyone.
