For those of us who like free

, Rocky Mountain Animal Defense has a kids' book about veganism that you can download & print out from their web site. It is called "What do you eat, if you don't eat meat? And other questions kids frequently ask" It is pretty cute with a bunch of color cartoons of animals saying "yea, I'm saved", etc. It explains gently what vegans eat & wear & why.
