Wow, you could always just tell your kids to pick out their 5 favorite toys, and bag up the rest (unless they miraculously decide to clean it up themselves!). My mom used to do that once a year or so (although she did keep stuff she knew was important to me, but I liked the dramatic effect).
Word. I cleaned the house today and skipped Lila's room.
This is just too close for comfort. I don't know if I am looking at my niece and nephew's bedroom or my own kids rooms :)
