Welcome aboard. I care for my older sister at our home. It works well for now and my husband is very supportive. My sister listens and does whatever he suggests. Me? Not so much but at least she is here and safe, eats whatever I cook and sleeps like a rock. You will figure out ways to make things easier. Siblings are hard to convince and I can’t count on mine either. There are lots of us on this discussion so ask your questions or solutions or rant any rave. We will understand.
