Proper intake of nutrients like folic acid, iron, and omega-3 fatty acids supports neural development, while avoiding harmful substances protects the delicate processes of growth. In the third trimester, the lungs mature, fat layers accumulate for temperature regulation, and the brain develops at a remarkable pace, preparing the fetus for life outside the womb.
