When children are infants, toddlers or even early elementary school kids, the reality of opposite sex siblings sharing a room is not super-challenging. There may be the issue of  "Do I paint the walls pink or blue?", but by and large, at those younger ages everything works itself out.

It's when kids reach their tween and teen years that co-ed room sharing can become problematic. And many moms--especially in an economy where most of us can't afford a huge house or apartment--are faced with this dilemma.

I have a good friend struggling with this right now and she's often at the point of tears. Her kids have loft beds at either side of the room, but that doesn't help anything when it comes to the matter of privacy and friends. Her teenage daughter hates being home because she can't stand being in her brother's friends' company. Her son hates having so many beauty products and girl stuff everywhere he looks.

What works best for my girlfriend now is giving her tween and tween "company schedules," that is, specific days of the week that either kid can have friends over. As for the beauty products, her son just has to get over it.

Are you a mother facing this problem? Do you have any suggestions for making life easier for a brother and sister who have to share a room? Do tell!
