it's more than just food and supplements, though that is a big part of it. it's just for moms, and talks about how pregnancy, breastfeeding and child rearing takes an enormous toll on our bodies, and we need to take really good care of ourselves.
the big thing i've taken away from it (for now) is that those minimum daily requirements listed on our vitamins and foods, are falling way short of what moms need. they have a chart in the book and on the site where they list MSDVs -- mother's suggested daily values! the prenatals i am (still) taking are good for some vitamins, but falling short on others, according to this. so as of today, i've started taking an omega-3 supplement, and a calcium-magnesium-zinc supplemt, and it looks like i need a b complex as well.
