As your first trimester comes to a close,your fetus (who seems to be working its way through the produce section) has reached the size of a peach, about 3 inches long. Your baby's head is now about half the size of his or her crown to rump length, but that cute little bobd is picking up steam and will continue growing overtime (at birth, your baby will be one -quarter head, three-quarters body). Meanwhile,your baby's intestines, which have been growing inside the umbilical cord, are now starting their trek to their permanent position in your baby's abdomen. Also developing this week: your baby's vocalcord ( the better to cry with... soon!).
