How the Baby's Growing After 12 Weeks

The baby's hit the 2-inch mark (about the size of a lime) and weighs half an ounce. Her face is beginning to look more human. Her eyes, which started out on the sides of her head, have moved closer together on her face, and her ears are near their final positions on the sides of her head. The baby's intestines, which have grown so rapidly that they protrude into the umbilical cord, will start to move into her abdominal cavity about now. Her kidneys are secreting urine into her bladder. Her nerve cells have been multiplying rapidly, and synapses (neurological pathways in the brain) are forming. The baby may have acquired more reflexes by now, including sucking, and she'll even squirm if you prod your abdomen, though you still won't be able to feel her movement for several weeks.
