My mother in law has Alzheimer's, my husband and my sister in law split the duties of caring for her along with an aide the we pay to stay with her during the day while they are at work. We have been doing this for a year since my father in law passed away suddenly. Stress levels are very high as we have families at home that need our attention also and fights between siblings have happened. My sister in law is POA and health care proxy. She is mad over a recent fight and has told us she is no longer available for in home care for her mother. She said she will continue with taking care of the bills and stay in contact with a program through Medicaid that she has been trying to get my mother in law into that will provide around the clock care for her (waiver program). My husband is now left with caring for his mother other than when the aide is there. My question is, if my sister in law is POA and health care proxy isn't it her job to find people that will come in to take care of my mother law if she is refusing to do so? What action can we take If any?
