Baby Development
The baby's movements are becoming more coordinated. Eyebrows and eyelids are fully formed. The baby is swallowing amniotic fluid and absorbing small amounts of sugar, helping the digestive system develop. If your baby is a girl, the vagina has begun to form. The baby's taste buds are working, and they can taste what you eat through the amniotic fluid.
Week 21 Highlight: Your baby can now taste flavours through the amniotic fluid - spicy, sweet, or bitter - whatever you eat!
