My mum is in care, my dad still living in his home (90 years old) with support from us 4 children in his care as he does not want "outside" help. We respect dad's wishes with his care but he is very controlling with mum who is in care. He stopped my sister and I taking mum out in the car for the day, so when we conceded and took her for a walk in wheelchair he put a stop to that. He has tried to stop us having family lunches (he is always included) on the verandah at the home by asking staff to lie and tell us it is not allowed! Now my mum is bedridden and kept in her room. We brought her a tv and the next day dad removed it. I feel strongly about mum's quality of life and when I try and discuss this with dad he just tells me I have no rights as he has Power of Attorney for mum. What is the best way to handle this situation? I will be most grateful for any suggestions.
