I just had to take a minute to give props to these books by Amy Wilson Sanger. I got them for my little one in order to keep her aware of all the variety out there, and they are just wonderful. They are small board books with cute food pictures made from other materials (hard to explain, just take a look at them). They are little rhymes and written for kids, obviously. Here are the titles:
Yum Yum Dim Sum
My First Book of Sushi
A Little Bit of Soul Food
Love them and highly recommend to chowhounds with baby chowhounds.
