Owen's current favorite "toy" is this empty tissue box. I showed him how to put his blocks in it yesterday and he's been carrying it around with him, searching for other small objects to put in it, ever since. He also enjoys all manner of empty containers. Currently, we have one cleaned out peanut butter and one applesauce jar lying around the house (he's playing with one of them as I type this). I'm glad he finds creative ways to entertain himself with items from the recycle bin, but it kind of makes the closet full of unwrapped Christmas gifts we've bought for him seem a little pointless.
