Fetal Weight Standard
During week 30, the baby's brain volume expands rapidly, forming deep convolutions and folds. The surface wrinkling maximizes neural connections needed for life outside the womb.
The bone marrow has completely taken over manufacturing red blood cells. The volume of amniotic fluid around the baby peaks around this time and will gradually decrease as the baby fills the remaining uterine space.
