Query: don't read this book!

this is the worst book on pregnancy and food ever written. any woman who has ever had any insecurities around body image will take one look at this book and realize it's the fault of books/ideas like "what to eat when your expecting" that we have issues in the first place. don't buy it, don't even borrow it, it'll just make you feel inadequate or fat!
