My dad lives alone and gets lonely. Had a fall and is currently in a transitional facility to get stronger. He's confused about why he is there and denies falling. He has no short term memory. My brother and his family are visiting in multiples. Tonight there were 7 people in his little room. They are boisterous people with good intentions. They think this is stimulating for him. Is family chaos OK or should I ask them to keep the group size smaller in visits?
