The Cauliflower Conspiracy

Has anyone read The Cauliflower Conspiracy? Did you find it at all helpful? There is also a follow-on book called "I only like Toast" (how appropriate!).

Now that DS is starting to understand a bit more, I am looking to start addressing his really awful fussiness with food from a reasoning perspective rather that a purely by offering different food a gazillion time a day (which will simply not be possible when his sister is born).

I have done heaps of research on the topic, but also feel like I need to gain a greater understanding of why he is doing what he is doing - and so am looking for reputable books and reading material. So if you know of any other "fussy-kid" books, I would love any suggestions.

Thanks
