Mom has advanced dementia. No short term memory at all. Bad balance issues and ankle arthritis. Lives alone next door to my sister, who works during the day. I live an hour away and spend two days a week with her to pay bills, make sure meds are in order, clean, laundry, and take her for doc appointments, grocery shop. Our brother, who lives about 30 minutes away, rarely visits or calls her, and is oblivious of her declining condition. She used to have a couple of whiskey toddies in the evenings (she and her late second husband got into that habit, and she continued it after he died). We thought it was not a big deal for her to enjoy a drink in the evenings to pass the time in her loneliness- but this past year, with her declining mobility, her drinking made her balance issues worse, and she had a fall in December - I found her the next morning after a night on the floor - the empty whiskey drink glass still sitting on the table......so I knew it contributed. No injuries, but that fall increased her cognitive and physical decline tremendously. She's now dependent on a walker, and can barely get around. The day she fell, I told her no more drinking. Poured out the remaining whiskey and told her we would no longer take her to the store to purchase alcohol. She has been mad at us ever since, but we explain that it's for her safety. A couple months ago, we found a bottle of whiskey hidden in a cabinet - our brother had bought it for her at her request. We gave it back to him and said she can't drink - a month later, it was back in the cabinet - he had brought it back to her. We took it again and poured it out. We reminded him that she can't drink. He just doesn't get it. Then I found another bottle yesterday - asked her about it, and she said she asked him to bring it to her - she started crying, because she'd been busted once again - I told her I wasn't mad at her - I'm mad at him for enabling her and not getting it - it's for her safety. He won't answer my calls or texts explaining that she simply cannot drink.....she overpours and drinks too much. He doesn't want to or doesn't seem to understand her decline and safety issues. Are we wrong to tell her no? We have medical and durable power of attorney. We do everything for her - for her health and safety. He does nothing and it angers both of us. Opinions?
