I am his POA he was to live with her on the temp basis. I recently asked for him to come back to my home. She stated that I am under a lot of stress and could use this break. The stress I am still under because she is spending his entire 2,800 each month on her family. She has had him for 2 months. If I try to take him, I feel that this will create a big family mess. What am I to do? Also, dad doctor require that a keep a daily log of his blood sugars and high blood pressure readings This is something that she does not do.
She's not going to like it, so be prepared if she no longer wants to take care of dad. Then you will have to consider respite care.
If your sister is considering her time while caregiving as something she wants compensation for then it is your decision as to whether you will pay her for her time. That may be $15-20/hr. Up to you on how this is handled if you have powers under POA.
