Girls, 11y and 14y, sharing same room
Recently my family has had to take in my wife's father. While temporary in nature, this has burdened the family slightly and caused my daughters to have to share a room. My 14yo daughter visits on a standard schedule but lives with her mother, and the 11yo lives here full time. We had a bedroom set aside for the 14yo to have her own place, etc... but alas is has been given the wife's father. Tension has already started between the two girls on sharing the room.
One of the conflicts currently happening is that the 14yo likes the room pitch black and quiet for sleeping... the 11yo sleeps with a radio/tv and light on. Literally night and day. I am evaluating the duration of my wife's fathers stay and whether to find a new location to live... but in the meantime does anyone have any recommendations on how to ease each of the girl's issues?
