My girls will be moving into the same room together after Christmas. I have started looking into bunk beds on Kijiji and noticed that a lot of people seem to sell "never really slept in" or "used for only "6 mos" bunk beds. What is your experience with bunk beds and your kids? Will they grow tired of them shortly after getting them? At what age did you find they out grew them? They currently both have their own beds but I think it will be a bit tight with two twins in there. They have slept in bunk beds twice before when we stayed in a hotel with bunks. They loved them then.
