By the end of the second month of pregnancy, the baby is about the size of a pinto bean and is approximately 14 to 20 mm long. The baby is developing at an amazing rate during these early weeks. Eyelid folds and ears are forming. The baby's eyes are still very wide apart on the sides of her head, but will eventually center themselves out. The tip of the nose is actually present at this time as well. On ultrasound you can see that the aortic and pulmonary valves of the heart are present. The tubes that lead from the throat to lungs are branching and the baby's torso is getting longer and beginning to straighten out. Just a few weeks ago, the baby's arms were tiny buds. Now the elbows are actually present and the arms and legs extend forward and have grown longer. Fingers and toes are becoming visible also.
