This is an important week because your baby is going from being an embryo to being officially a fetus. It’s a medical term which means the most critical part of the development of the baby has almost come to an end. The main structures and organs are formed and now they are going to grow fast and fine tune their functions. His growth may now be measured in weight because before his size was too small to determine with accuracy.

During these weeks your baby will be the size of a small plum (1 inch and a half or four centimeters). The shape of your baby is definitely human and besides having limbs, he also has shoulders, knees, elbows and fingers on his feet and hands.

Nevertheless, his head is still by far larger than any other part of its body. This difference will level out in the following weeks due to the fast growth of his body.
