Option 3 : expensive and u & your mom cant see your dad. This is bad.
Family members can visit the resident everyday during visitation hours. Furthermore his dad can make new friends and take part in various social activities and group therapy exercises. Better than staying at home watching TV.
Another option for TS is senior day-care centers. Father can participate in social activites & physical therapy during the day when everyone is at work, and go back home in the evening to be with family members.
