I've been encouraging First Son to play or read on his own during nap time. I'm hoping to make that some time I can devote to my own pet projects (or exercising, which isn't as much fun but is supposedly good for me). When I gently but repeatedly refused to make a play-doh octopus for him, he finally made one himself.
And a fine octopus it is, too.
Then the hippo ate it.
