Ever since I put all of Hudson's books out within his reach, he has made a new game of throwing them all out of the basket. He may or may not even decide to look at one. He also enjoys putting one or two back, but leaves the majority scattered on the floor. That's one of his new things, putting smaller object inside of larger objects, as well as stacking items. I don't mind the mess. I hope one day he'll enjoy books for their real purpose.
