my sister has 2 girls 5 and 8 and they share a room. The each have a side with beds and dressers and toys. they get to pick posters for their own side to show something they like because they are very different but they like that they each have their own decorations. It isn't easy I am sure, I have a 12 and 13 year old boys that when I have them together every other weekend sometimes it is a struggle with them. Good luck.
