At this point, your baby can officially be called a fetus and measures around 9 inches. The tail is gone, and the structure of the body, while not 100% formed, already exists. The legs grow, and the little buttons that will become fingers begin to appear. The liver, gallbladder, spleen, and adrenal gland are developing in full force. From now on, your child will start gaining weight and size at a more accelerated rate!
