Originally, our two oldest had their own rooms, but Stat Boy kept crawling into Karate Kid's bed at night, so we gave in and moved his bed into her room. Today, we have our master bedroom and three smaller bedrooms. Stat Boy has been on his own for several years now, but will eventually gain a roommate, whenever Baby Wingnut is ready to move out of our room. The girls are all paired up in the remaining two bedrooms with two girls each to a queen sized bed. On weekends and during the summer our kids prefer to all sleep together in the basement on piles of blankets and cushions they have acquired over the years (they are all a little weird, I know).
With our oldest turning 16 and our next oldest daughter approaching her teen years, I began to think, possibly, a 16 year old would not want to continue sharing her bed, let alone bedroom with a nine year old. After discussing options with the girls and Wingnut, we went ahead and purchased a trundle bed to replace the queen bed and we are redecorating the oldest girls' room to accommodate the increasing maturity in our family. As much as I don't want them to, our babies all grow up, hopefully they'll still want to continue having their slumber parties in the basement.
