i have a 4 bedroom house and there has been talk of my partner moving in, in the near future. I have twins a boy and girl who are 8 and they currently have a room of their own. My partner has a 14 yr old daughter and 12 yr old son and has them 3 nights a week. But unless I make some drastic changes to the house then there arent enough bedrooms for everyone. What does everyone else do in similar situations? Is it unreasonable for my son to share a room with his son?
