20 Weeks Pregnant
You've reached the halfway point! Your baby is now the size of a banana and is becoming very active. Their skin is covered in a white, waxy substance called vernix caseosa, which protects them from the amniotic fluid. This is also a major week for sensory development; the brain is designating specialized areas for smell, taste, hearing, vision, and touch.

- The fetus is actively swallowing amniotic fluid, practicing for digestion.
