So now that The Child is mobile, I have had to re-assess where she plays, and what all is lying around when she's exploring the floor. I figured a basket of laundry was relatively benign, and posed no threat. I was right. What I didn't count on was her pulling up on said basket of folded laundry, and, piece by piece, throwing everything out of the basket while I spaced out for 30 seconds and checked my email. Point: Baby.
Lesson learned: although the basement play zone is baby friendly (except for the entertainment center....not sure what to do about that), folded laundry in that zone will not stay folded for long.
