Fetal Development
Second Trimester
Week 14 – The baby is now approximately 5 inches long. His limbs are developed. Fine hair grows on his head and genitals are visible. The baby can turn his head, stretch, raise his eyebrow, wrinkle his forehead, and hear.
Week 16 –Many pregnant women will begin to "show" at this point. The ears are functioning and there is increasing evidence that the baby can hear many things: his mother's voice and her heartbeat as well as noises outside of his mother. The umbilical cord conveys 300 quarts of fluid per day.

Week 18 – The baby is more than 6 inches long and can suck his thumb. This practice is preparation for feeding after birth. The skin is so transparent that you can see the veins. The baby is very active and energetic and can go through the motions of crying as the vocal cords are developed, but without air they cannot make a sound.
Week 23 – At 5 ½ months, the kidneys are starting to work and the air sacs of the lungs are developing. The baby is proportioned like a newborn. The lips are distinct and the eyes are formed.

Weeks 24 to 26 – The delicate skin is protected from the amniotic waters by a special ointment called vernix. The eyelids have become unsealed and the eyes can detect light through the mother’s abdominal wall. Virtually, all the brain neurons are present. The baby drinks the amniotic fluid and would survive outside the womb if born early.
