Around your baby's skin a white cheese-like substance begins to form called the vernix caseosa. This protects the baby's skin inside of the uterus from the harmful effects of swimming inside amniotic fluid for months on end. The baby continues to grow, and the placenta grows along with it to nourish the baby. Though your baby is about seven ounces, it will weigh more than fifteen times its current weight once it is ready for birth.
