My dad has beginning dementia and we are paying my sister 2k plus 1k for caregiver a month to care for him at her home. We just moved him out of his house so we havent told him he is paying for this out of the limited funds he has. The plan is for me to fly in next month to discuss finances. My sister is now telling me he will freak out and that i shouldnt tell him at all or tell him half the amount. I am in charge of his money. I feel I have to as he totally trusts me. She says he has become more paranoid about money and he should actually, he doesnt have much left. I feel i am stealing from him and she feels she will have to deal with his stress and comments that he is paying his daughter to care for him. 90% of the time he is fine, but that 10 - 20% he is confused and clearly cant live alone. Should I tell him or not?
