Well, my wife is 17 weeks pregnant, and yesterday we found out that we are having a boy!! We are very excited (me especially), and the best news was that the baby is developing normally. I've attached some pictures, you can really see the development of his spine, legs, arms, and skull in these pictures. It is truly amazing that even though he is a little less than a foot in length and weighs about half a pound you can see all these body structures. We discussed prenatal development in class a few weeks ago and it is really cool to be able to see this in your own child. By this point, his brain configuration is nearly complete, his heart muscle is developed, and he has begun motor activity. The skeleton, which begins as a cartilage model, is beginning to ossify. Many other changes will occur during the next five months until we welcome him into the world.
