My girls technically have their own rooms. But my 9 year old has 2 twin beds in her room, so her 7 year old sister has been sleeping in there for years, by choice. Luckily I have the option to separate them if need be (as in "If you two don't go to sleep I'm separating you!!") but I rarely do it. It's actually the 9 year old who can't stand the thought of her little sister not being in there with her. Sometimes when I walk by their slightly open bedroom door I listen to the chatter. It's absolutely a beautiful thing. I think the memories they are making will be priceless when they are older. They tell stories, and the other night I actually heard the older one trying to teach the younger one multiplication. Too funny :)
