There's a whole genre of cookbooks dedicated to making food that's fun and cute. Like the pastry challenges on the Food Network, but way less complicated (and without that nasty move-it-from-here-to-there part that's obviously designed just to add a little drama to the proceedings).
As Dixon gets older, I see myself doing more and more of this. He's already so into what happens in the kitchen - he loves to watch me cook and whenever we're visiting friends who have a kids' kitchen, he spends hours pretending to saute waffles or microwave cans of peas or whatever. When I used my classic cars cake pan to make him some tiny cakes, he freaked out. I can only imagine the reaction a caterpillar made of Hostess sno-balls would elicit.
