Playing with his favorite toy - stackable wooden rings - gets a whole new dimension when placed into a plastic tub. Put them all in, snap on the lid, and watch the synapses pop and snap.
Eli tosses it around and listens to the familiar CLACK the toys make when they smack into each other. I left one corner of the lid ajar. Finally he got the lid off, grabbed the big bead necklace he likes to chomp on, and waved it around victoriously with a big grin on his face.
Then, we did it again. And again. Good times.
