Your child is now the size of a mango! A cute little mango that has gone from the primordial stage to sensory development. The brain has been actively working, especially the areas responsible for the senses: odor, palate, hearing, vision, and tact. Hands and feet have taken their shape while the skin produces a waxy, cheese-like layer called the vernix caseosa, composed by the oils secreted, dead cells, and lanugo, the thin hair that coats the body. The vernix protects the baby’s skin from floating around in the amniotic fluid. That yellow-ish goop that covers a newborn when it comes out of the uterus is the vernix.
