Background is that i have POA for mum as she trusts me making decisions which i feel are best for mum Have a crazy sister who has never helped or been involved in mums care. She has recently been seriously ill (my sister)a couple of times and i think wants to try to make up for this a bit and also needs the emotional support for herself from mum.She has been overheard telling mum she wasnt there for HER when she needed her and upsetting her. Also that she will get mum out of the care home and back home. Lots of false promises she cannot deliver.Mum is unable to give her support as she does not have the capacity to do so.Mum is very confused by all of this and it is affecting her general well being. Sister wants to take mum out of care home to visit dad in their marital home. I think this is crazy because It will confuse mum, shw will think why can't she stay in her own home She will become settled and not want to leave It will upset mum and she may become angry and refuse to go back It will trigger lots of emotions and upset Mum would not have anyone to help he mobilise or go to toilet as dad and sister are not capable due to their own health problems I have said No to this request as i do not feel it is in mums best interests. But I am feeling guilty for stopping this. I have suggested they go somewhere more neutral but my sister is adamant she wants the right to take her back to her old home. she has not been home in over 2 years. Am i being unreasonable?
