Your baby this week
By 20 weeks your baby's skin is covered in a white, greasy substance called vernix. It's thought that this helps to protect the skin during the many weeks in the amniotic fluid.
Your baby is already practicing for his/her first breath outside the womb, moving his/her chest up and down as if he/she were breathing through the nose. The genitals are now fully formed.
By this week your baby weighs just over 300 grams and measures approximately 26 cm long from head to bottom and about 10 inches from head to heel.
