We didn't want to find out. At the very beginning, I think deep down I thought it was a girl, though. (She is!)
At the 20-week scan we told the consultant that we didn't want to know. We also found out LO had a clubfoot, and from that point I kind of assumed it was a boy, because I'd never heard of a girl with a clubfoot and it is statistically more common in boys. I felt kind of surprised by the idea of a boy, but pleased.
After that scan, when DH and I were still kind of reeling from the news, we were walking around between appointments, and he said, "Well, what really gets me is that we were very clear that we didn't want to know, and the consultant told us the sex!" I said, "He did?" I completely missed it. DH didn't tell -- he kept it a secret for 20 weeks. I just assumed the doctor said "he" rather than "baby," not meaning anything.
Sometimes when we were talking about names (both lists), I would say, "Wait, but don't you know?" He discussed boys' and girls' names with equal weight. The more time passed the less certain he was about what he'd heard, too.
At the birth, the doctor exclaimed, "It's a girl!" I said, "Really? A girl?" I thought there must be some mistake. I asked DH, "Is that what you thought all along?" and he nodded. Apparently the consultant at the 20-week scan had said, "Your daughter will have a completely normal life." And I missed that!
We are through a lot of the clubfoot treatment but still a bit to go -- she does seem to have a pretty normal life, though!
And I think it's sweet that her daddy knew that she was a girl and kept it his own secret.
