My 89-year-old mother recently moved in with my sister. I live in Texas, my sister lives in Florida. She has grown children and I have teenage children living at home. I call my mom everyday and try to be supportive of both she and my sister. My mother had to move due to health reasons. What is reasonable for me to offer as assistance to my sister? My mother pays her a monthly stipend to live there and my sister provides for many of her needs. Mom is ambulatory but does need assistance with daily living needs. They are being to get on each other's nerves, and I feel caught in the middle. I would like to help but am not sure how. I plan to travel to Florida every 3-4 months to offer a week's relief to my sister. What else can you suggest I do?
