Query: DO NOT BUY THIS BOOK

I am the mother of a 15 month old now and everytime I have referenced this book, it has been inaccurate with something. Hep B according to every other source is an immunization that children should receive whether the mother tested positive or not; this source states it as optional. I have the mayo clinic book and what to expect the first year and toddler years and they have proven to be the most accurate. I would not trust this book.
