A man has moved into the adjacent room to my loved one a couple of weeks ago. The other morning he was found lying in beside her, on top of her bed. She is very fragile and has been bedridden for more than a year. He managed to get over the bed rails and lie beside her. I am so worried that she could easily have been smothered. The action plan is to put him on 15 minute observations, but it would take less time than this to seriously hurt her. What can I do?
