My mother in law gets "stuck" doing things. Like stirring her coffee, she will continuously do so for 10 minutes straight. My husband will say mom six times and she ignores him or does not hear him (I am not sure if it is one or the other). There are many times that she will be doing something that when asked to stop or if we try to redirect her she ignores us and continues whatever it is she is doing. I do not want to yell at her to get her attention but I don't know what else to do.
