Hello this is my first post, but could really do with some advise. My partner and myself have my mother living with us as she has dementia, she has lived with us for over 2 years. We have an excellent care package and a brilliant social worker. The problem is my sister, she lives in Australia and comes over for about 3 weeks every year. Last year was a nightmare, as she was taking mum out every day and totally exhausting her, and causing her to get upset. It got to the point where I eventually threw her out of the house due to her severe attitude problem. Anyway she is back again this year. She arrived on Sunday, and she came round for an hour just to see mum. Whilst she was here we all sat together whilst we discussed the current care package to her and she agreed that it was the best thing to keep mum in her regular routine. This lasted 2 days, on the Tuesday she took her out, despite been told that she needed to be back for 2:00pm for her carer visit, she arrived back at 3:30, with a very distressed mum. When I confronted her as to where they had been, she replied that they had been to the local park and had some lunch. I knew there was something more an could tell she was lying. Yesterday she turned up, and I asked her straight if she had taken her to see my brother, who was another reason for mum living with us, as he got her evicted from her flat, and would steal money off her. She replied yes, and then started saying that everything was my fault, and that she was never consulted on anything regarding mum. What I really want to know, is can I prohibit her access to mum, as she lives in my house, and considering that every time she visits mum get's very unsettled.
