I have been remiss in thanking you all for your advice. I've read everything you had to say and more, and I've done...nothing.
Well, almost nothing. I've adopted this basic plan: I've stuck to whole milk, but reduced the amount she drinks (from roughly 24 to 18 ounces per day). I've been choosing snacks and foods that are lower in sugar (for example, oat bran pretzels instead of animal crackers). I've been serving her vegetables as the first part of her meal and experimenting with different preparations (right now we're big into roasted carrots and zucchini).
We'll see what happens. If you have further thoughts on the subject (beyond, "My God, you've been giving her animal crackers?"*), I'm all ears.

Otherwise, I spend most of my time wringing my hands over the state of the economy and the election and the same things everyone else is worried about. Our apartment in Brooklyn is on the market, which is such spectacularly awful timing that it makes me laugh when it doesn't make me weep.
As my husband observed, no one's going to buy an apartment (even one as lovely and well priced as ours) without the Bailout. Is anyone even lending money anymore? Yet I'm still not sure I can really get behind it. I mean, I never even took Econ 101, but aren't free markets supposed to be free? Aren't complete financial meltdowns the (incredibly high) price we have to pay for that freedom?
