Written by Courtney Adamo and Esther van de Paal, 9 Months is a month-by-month guide to pregnancy for the family to share. How does a baby grow from a tiny egg? When has it grown to the size of a lemon? When does its hair grow? At what point is the baby able to hear you if you talk to it? Now you can answer all of these questions!
