I know my kids are 9,7, and 4, but they still like to all sleep together in the same bed----a twin bed, at that. I don't know how old they will be, when they just decide that this is no longer something they want to do. However, I had to try to catch a picture and share it with you. I have a feeling they are going to be running out of room very shortly. By the way, we only allow them to do this on the weekend. School nights require a good night of sleep, which also requires some space (according to my logic).
