I'm hoping this is the right forum for this question, bed related right? I think eventually we'll be getting bunk beds for our DD's. But I'm not sure what age would be appropriate for sleeping on the top bunk. I remember having one for awhile when I was like 10 & my brother about 6 (me on the top bunk & him on the bottom) but I think we could've had them years earlier than that. What age did you put your DC on the top bunk?
