Baby's development - 20th week

A substance called vernix protects your baby’s skin as it is getting thicker. If your baby is a girl, her uterus is formed, her vagina is developing and tiny little pink nipples are appearing on her mammary glands. The cells responsible for each of the five senses are developing in your baby’s brain. Soon, a whole new world will open up for him.
