At 12 weeks your baby is approximately 2 inches long, and weighs approximately .50 ounces(about the size of a plum).
Your baby's fingers will soon begin to open and close, its toes will curl, the eye muscles will clench, and its mouth will make sucking movements. In fact, if you prod your abdomen, your baby will squirm in response, although you won't be able to feel it. The intestines, which have grown so fast that they protrude into the umbilical cord, will start to move into its abdominal cavity about now, and the kidneys will begin excreting urine into its bladder. Meanwhile, nerve cells are multiplying rapidly, and synapses are forming furiously in your baby's brain. The face looks unquestionably human: the eyes have moved from the sides to the front of the head, and the ears are right where they should be.
Note: Every baby develops a little differently — even in the womb. This information is to give you a general idea of your baby's size.
