Baby Development
A waxy coating called vernix caseosa is forming over the baby's skin to protect it from the amniotic fluid. The brain is designating specialised areas for smell, taste, hearing, vision, and touch. The baby is becoming more active and may establish a sleep-wake cycle. Sensory development is in full swing with nerve connections multiplying rapidly.
