Looking to blend 2 families together in a new house, there will be 4 bedrooms, master bedroom for us, then 3 bedrooms. We have 4 kids (dp has 3, i have 1 - all the same gender) at the moment his eldest has his own room, mine us the next eldest and has his own room, his younger 2 share a room. So this is the same arrangement we are planning in the new house. However, it seems to be 3 bedrooms are a decent size and the 4th is usually time - just room for a bed. So how do we sort out fairly who has the tiny room?!
