Mom lives w/ sis but stays weekends w/ me and husband. She performs repetitive tasks over and over. (Folds and re folds clothing or blankets. Clears things from L.R. coffee table and puts them in random piles) Could it be a soothing mechanism for her? I have pulled up family pictures to stimulate some interest, but she gets bored. Any feedback would be appreciated. She can go for short walks. How can I help to fill the days for her?
