Oprah's favorite doctors, Michael Roizen and Mehmet Oz, return with a comprehensive guide to pregnancy and birth which promises to answer the numerous questions every expectant mother has, including the ones she hasn't thought of yet. Roizen and Oz offer a step-by-step guide which takes future parents from conception to delivery, explaining the biological changes which are occurring to both mother and child as the baby develops. They also outline specific plans for diet and fitness, explain the pros and cons of anesthetics and epidurals, provide insights on the psychological changes a pregnant woman commonly experiences, and detail the emerging science of epigenetics, which may allow parents to improve the future health of their unborn child.
