First Meals, by Annabel Karmel

This cookbook provides easy recipes for puree's, shakes and more.

It also provides a great guide for what you should introduce to your baby at each phase in development. The photographs are beautiful, with vivid colors of fruits and vegetables. It also includes recipes and presentation ideas to help entice the pickiest of toddlers.

I have provided a link to the expanded addition above.

Deceptively Delicious by Jessica Seinfeld

Toddlers can be picky eaters. This cookbook, by Jerry Seinfeld's wife, includes simple recipe's to sneak less desirable vitamin rich foods into their favorite dishes. Think avocado chocolate pudding and grilled cheese with butternut squash or broccoli puree. It sounds strange but your kids will love the recipes and benefit from the nutrition and calorie cutting.
