When I was pregnant with my first kid, I got a few library books to learn about how to be more "green." Why? Well, I was reading about detoxing and the effect of too many chemical and foreign substances on the body, over time. Well, did you know Utah has horrible air and that alone contributes to many respiratory issues, along with many other health issues. (side note)
And I think this second one even had a few homemade baby food recipes, which was kind of fun.
