How do I get my sister to comprehend the safety of my mother?
My sister will pick my mother up for appointments and church to transport her and mom has four stairs to descend and especially now that the weather is getting frosty the steps can ice up. My sister has to come up on the porch to get my mother's walker to load into the car but then my sister proceeds to get into the car and lets my mother descend the stairs alone without supervision. Mom is always carrying a purse in one hand and is very unsteady. I have addressed this with my sister numerous times even as recently as five days ago. Yesterday I was visiting my mother, my sister picked her up for church, my sister got the walker, got back into the car and, once again did not supervise mom. I stayed back a few seconds to see if she would since I had just addressed it but when I saw her get back into her car I quickly went out and spotted mom on the steps. I am at my wits end since I live over an hour away and my sister lives five minutes from mom and does most of the transporting. My sister just doesn't get it. Do I go ballistic on her to get the point across or wait and let something happen?
