scans of 1st and 2nd baby - please compare :)

I have been driving myself MAD trying to look for my first baby's scan picture so I can compare. I have finally found it and now I\m not sure it shows a nub? What does everyone think? I will post my first baby first and my current pregnancy second. Will be interesting to see what people think?

Baby No 1 Attachment 11579

Baby No 2 (current pregnancy, sex unknown) Attachment 11580

Im going to guess both boys?!

Not sure I see a nub in #1, but #2 looks girly to me. But I am no expert!!

No 2 looks very girly :)

No 1 is indeed a boy, no 2 is a mystery :) x
