I recently read a book called Healthy Snacks for Kids by Amy Wilensky. It's part of the Knack - Make It Easy series of books.
This is a cookbook, but it also offers tips, ideas and nutritional information. I don't always believe everything I read about nutrition in the mainstream media, but most of the author's advice seemed solid to me. I did find her tone just a little off-putting and it seems like she mentions Greek yogurt at least once in every 2-page spread. That's ok. I like Greek yogurt,...and don't have to like the author to like the book.
I'm trying to let go of some of my cookbooks, not bring more in, so I'll probably just return this to the library and not order a copy for myself. It's tempting, though. I found a lot of great new ideas for snacks -- and lunches -- not just for Kat, but for the whole family. The book has lots and lots of pictures, which is a must for a cookbook to catch my eye these days.
Overall, I think this would be a good addition to anyone's cookbook collection, but especially for those who have kids.
