My mom is in assisted living and everyone is kind and helpful, but one caregiver is especially good. She seems to have a little more involvement with my mother and she has tipped me off more than once when she felt something needed my attention. I've expressed my appreciation to both her and her supervisor, and I try to do something special for the entire staff every so often. But I feel like this person is just a little more concerned about my mother's well being. I'd like to do something for her, but I guess I worry about excluding the others. Any suggestions?
