Query: An Excellent Reference

This is an excellent book when used more as a reference than a month-to-month read. I started reading it each month and it covers so many topics it can make you paranoid. So, I started to just look up topics as I experienced them and was glad to find all the helpful answers I needed. This is a must-have for any pregnant mom-to-be.
