Big Girl / Doll house bunk beds

I have had my eye on this bed since the girls turned 1. They are quickly growing out of their toddler beds. But I'm still worried my little monkey's will use it as a jungle gym. I imagine the worse ... always. Maybe I will wait until this time next year when they are 4?????? So what if their feet stick out of the bars at the end of their toddler bed by then. But then I think ... what if they stop making this bed. I love it! Perfect colors for their room and what little girl doesn't want a doll house for a bed!
