She is currently curled up,
She lined it with a pillow (which filled it as if it was meant to be the mattress of this infant-sized crib) climbed in, and pulled her blanket over herself. She is sound asleep in the box on the bed, and my son is asleep on the bed beside the box.
Mom, you once voiced your concerns to me about the portacrib being a little small for her. I don't think we'll have any problems for the next ten years. For her 13th birthday we'll just need to find a bigger box...
