Wondering what the guesses are based on the nub theory. i think its a bit hard to tell with the curve of the spine. The potty shot looked girl (3 lines). But do they all look this way from that angle at 12 weeks? I enhanced the photo to make it easier to see from the side. Id love a guess and to know how confident you are in that guess!http://i1225.photobucket.com/albums/...fileofBaby.jpg
