Last weekend was Easter, which (since we're not what you'd call religious people) involved egg dyeing, egg finding, stashing a basket of candy in Liam's room while he was sleeping, letting him eat jellybeans at breakfast, and gardening. It's Wednesday night, and we've still got most of a chocolate bunny and a couple of chocolate eggs in the kitchen cabinet. Heck, we've still got halloween candy in the kitchen cabinet. Are we stingy with sugar? Sort of, but we (C and I) are also kind of forgetful, and Liam seems to have picked up the out of sight-out of mind gene. He doesn't ask for candy or sugar much, in my perception, and we've been letting him have easter-basket candy when he asks (as long as he isn't tired or otherwise unlikely to handle a sugar rush well).
The philosophy we've been aiming for in general is that of course we have sweets sometimes, but it's not a big deal. This is just one part of an overall philosophy that's at least a little informed by Ellyn Satter, where we aim for intuitive eating, an acceptance and enjoyment of variety, and nutrition (integrated over every day or two). There's some conflict with Liam's kindergarten's philosophy, which has a very black-and-white "healthy"/"not healthy" food classification, while I have no interest in endorsing cultural messages about food and morality.
Of course he'll change as he gets older, and who knows whether he'll broaden his tastes, or how many all-cheese or no-veg phases he'll go through, but for now we're all about emphasizing what we like about food, the pleasure of cooking for oneself and for friends, and the good it can do for your body. We'll just have to see whether he winds up with as many forgotten things hiding in the back of the pantry as I tend to have.
