Week

Growth is rapid during the sixth week. Your baby triples in size. He or she starts to show basic facial features. Optic vesicles, which later form the eyes, are beginning to develop. Passageways that will make up the inner ear also are beginning to form. An opening for the mouth is formed by the ingrowth of tissue from above and from the sides of the face. Below the mouth, where the neck will develop, are small folds that ultimately will become your baby's neck and lower jaw.

By the sixth week of your pregnancy, the neural tube along your baby's back has closed over. The brain is growing rapidly to fill the now-formed, enlarging head. Your baby's brain is also developing distinct regions. Some cranial nerves are visible.

In the front of the chest, your baby's heart is pumping rudimentary blood through the main blood vessels and beating at a regular rhythm. The beginnings of the digestive and respiratory systems are forming, too. In addition, 40 small blocks of tissue are developing along your baby's midline. These will form the connective tissue, ribs and muscles of your baby's back and sides. Small buds that will grow into your baby's arms and legs are now visible.

By the sixth week of your pregnancy, four weeks after conception, your baby is about 1/8 of an inch long.
