My husband along with his brother are taking turns taking care of their father who recently arrived home from the hospital after having a lobe removed from his lung due to potential cancer, not cancer. Now he is re-cooperating at home. It has been challenging for them both, especially when the father is criticizing them on almost every task. This is wearing them down, any suggestions would be helpful. My husband had suggested a rehab facility for him to re-cooperate before bringing him home, other family members opposed the idea and brought him home.
