The boys were overjoyed when I made a fort for them in our front living room. I left it up for two days and then dismantled it - it is in our front room. It didn't stay picked up for long. I went upstairs this evening and when I came back, Ben had ingeniously put it back together in his own way. My front room has been overrun by little boy stuff!! Somehow, I will prevail and move the fort into the basement. There may be tears, but I will prevail!
