30 weeks pregnant
Third trimester about 6 months
At 30 weeks pregnant, your baby is about the size of a cabbage.
Baby this week
About 40cm. The baby has a fully developed brain with billions of neurons. Lanugo (fine hair) is disappearing and the baby is filling out with fat. The hospital bag should be packed.
Did you know? By week 30, the baby has completed approximately 75% of brain development — but brain growth continues significantly after birth for the first two years of life.
