Ellyn Satter is my favorite authority on pediatric feeding issues. All of her books emphasize a healthy division of responsibility: you're responsible for what is served and when you serve it, and your kids decide what and how much they eat.

In general, childrens' bodies know better than we do how much they need to eat for appropriate growth, and this division of responsibilities helps you avoid mealtime battles, and promotes healthy eating choices.

However, while her advice on feeding issues is great, her nutritional advice does leave a bit to be desired for folks making for progressive diet choices (organic, veggie, etc) for their family. This is her most popular, and comprehensive book.

Her classic book on "feeding dynamics", and how to avoid power struggles over food.

Satter's most recent book, focused less on picky reluctant eaters, and more on overweight issues.

Another good pediatric nutrition book, featuring research-based concepts of "metabolic programming" - how what we eat early on can influence influence cellular functions in ways that affect intelligence, personality, immunity, strength, and, of course, growth patterns.

Great book for adults and adolescents. One of the more solidly research-based books out there on nutrition, although there are a few arguments here that may be a bit ahead of the research. Their website is truly excellent as well.

I don't have this yet, but it looks practical, reasonable, and fun.

We really like this book for uncomplicated, healthy, & tasty recipes for baby and toddler foods. WholesomeBabyFood.com and FreshBaby.com are also great resources for making your own baby food.
