Update: we are having a boy, ETA 4/15/07. We went for a stage II ultrasound two weeks ago, because unbeknownst to me, there was a "problem" with the first one my wife had.

Turns out the fetus has renal pyelectasis, which is a soft marker for Down's Syndrome. There are apparently 12 "markers" which may indicate a chromosomal disorder, and the ultrasound showed only this one (which is a kidney disorder). The doctor indicated that the kidney thing could resolve itself as the baby develops further, or it might indicate that he has Down's. They can't tell for sure without doing an amniocentesis, which presents significant problems of their own. My wife is optimistic, and is trying to assure me that the doctor has to tell us that there is a risk, however slight, in order to cover himself. But I'm freaking out regardless.
