Melissa has ended her long, practically-entire-pregnancy-long blog silence about a week before her due date. She and her husband are way more patient than either Brian or I, so they have elected to not find out the sex of their baby. Go to her blog and vote on whether you think she's having a girl or a boy (she put a lot of pertinent info on her blog to help you decide).
I would have said boy, because many things from her pregnancy have been similar to mine except that hers did not involve a big pink cast. However, I know three other people who are pregnant right now and they're all having boys. So I think that statistically, we're due for a girl. We'll see!
