Today we opened the envelope. As of the last ultrasound, it would appear (according to the tech, because --believe me-- I can't tell much from the photos included) that we're expecting a baby boy! And, as I suspected, we will now need to work on finding a boy name since my brilliant choices for girl names will likely have to wait more than another 18-20 weeks to be put to use. Not the worst type of problem to have by far.
Christmas vacation continues to go wonderfully: sunshine, surf, lots of reading of books that have nothing to do with work (four books down, searching for another to sink into soon).
