I have a 3,5 years son already. At the scan, the lady told us girls :) This might be, because I read, this type of photo is not good, only the one, where they lye on their back. But unfortunately, we do not have one such... :( We have a video though, where there is a part, where one is in the right position, and on that I see that nub almost straight.Soon, we will find out. As I know it for sure, I'll tell. Quite excited!!!!
