We found out yesterday. We ended up with 4 pictures; the money shot of course, your standard side-view of him actually looking like a baby, a really funny picture where he looks like he's flexing, and one of him looking directly at the camera.
I'm assuming that the fact that he looks like an alien in the fourth shot is standard for 20 weeks. At least, I'm hoping that's normal.
Due date is a solid April 9th. I can honestly say that I felt like the happiest man alive when I saw that little weiner's weiner.
