The only thing kids may like more than playing with their food is playing with their play food: stirring plastic doughnuts into a soup pot full of wooden sausages, perfecting their rubber eggs, clattering around in a faux food frenzy. Culinary doodling lets kids in on the alchemy of cooking: the chopping, the dicing, a little of this, a lot of that.
So there's all that nice tactile busyness. But playing with food is also a highly social activity — and therein lies it time-honored appeal. As the anthropologist Claude Lévi-Strauss noted, civilization itself was built when hunter-gatherers moved from eating raw food to cooked. Creating meals together and sharing different ways of preparation led to more communication, then to campfire dinner conversations about the best dry rub for roasted mastodon.
In his kitchen, your child is likewise a social animal — alternately the most gracious host (vegetable stew all around!), the most contented drudge, and the giddiest control freak ("Finish your peas, Mama! I said finish your peas!").
