She is moving to Binghamton, NY. My sister feels she can give him better care but she will be working during the day where as where he lives presently he has resided for 40 plus years. He knows his way very well around his old apartment (kitchen, bathroom, his bedroom). Also I just found out that my sisters' new place has a stair case of 6 steps that lead up the bedroom and I try to make her aware that he likes to wander in his apartment several times during the night after he first goes to bed meaning that he may get up at 1 am, 3 am or later. I am concerned about his safety. Is there anything I can to stop her from taking him.
