What period of pregnancy does the baby develop the most rapidly?
Pregnancy is broken down into three trimesters. The baby develops most rapidly during the first trimester (weeks 1-13). The baby starts off as a collection of cells that develop into an embryo. At 8 weeks, the embryo is called a fetus because the baby resembles a human. At this time, all major organs and systems have been formed. During the second trimester (weeks 14-26), the organs and systems start to mature. During the third trimester (week 27-40), the baby starts to pack on the pounds.

Majority of this happens in the first trimester and continues till term. At the end of the first trimester all vital organs including the heart will have taken shape. (The foetal heart and the circulatory system is structurally a bit different from that of the adult and the lungs is a solid non-spongy organ with no air in it).
