I have a basket for our board books. They are all such funny shapes that they don't fit on the shelves very well and I wanted them separate so Esther could easily find them.
One morning I put a blanket on the floor and told all the kids to stay there and read books while I went off to get something done (I believe the project of the moment was getting dressed). They did a pretty good job obeying... When I came back they were still there and the toys were still put away, though the little chairs had been moved and they each had a blanket.
As I helped them put the books that they had looked at away, I told them to put the board books in the basket. That's when I heard Lucy say, "I'm bored of this book so it goes in the basket."
