I don't read much nonfiction, but I do worry about giving the kids a healthy relationship with food, since my relationship with sugar is....not...good. I have to say, Fearless Feeding is excellent. It answers so many questions, and I would recommend it for ANY parent. My favorite thing is that they take the time to reassure us not to overthink it - for example, the authors look at the whole make-your-own-baby-food craze and suggest that if we're really not into it, we shouldn't feel bad, because it's not that big of a deal to buy purees for the 2-3 months your baby eats them.
One caveat: the thesis here is to just present good, nutritious foods, and your child will eat them instead of junk. That seems a bit pat to me, and I would have liked some more detail about how that exchange will actually work. Because in my mind, it sort of looks like me presenting nutritious food, and her begging for junk for the next 48 hours or until I lose my mind.
