The First 9 Months booklet takes you inside the womb for a week-by-week look at the development of a human life. Did you know that a baby's heart begins to beat just 21 days after fertilization? Or that a female fetus, at week 16, has eggs forming in her own ovaries? This newly redesigned booklet is approved by The Physicians Resource Council and is a perfect educational resource for doctors' Offices and pregnancy clinics. It's a photo gallery of wonder few ever get to see.
