My daughter and I are about a month + into newly taking care of my father. She is the primary caregiver and I visit daily or every other day to assist. He had a surgery several months back and has since recovered, but is still struggling with his balance at times. We are both, as well as her husband and children, trying to adjust to this transition to a new home with an elderly man who rarely has anything nice to say and is constantly complaining and barking orders. Any advice?
