Comparing scans from 1st and 2nd pregnancy

[HRHXO]

I've been looking at my 12 week scans from my first and second pregnancies and trying to see if they look similar at all. Can anyone guess genders from either scan? I can't wait to see if they will look alike!

Just for fun I'll say girl top, boy bottom.

Basing that mainly on the skull shapes - top looks very rounded like both my girls scans. Bottom is more squared off and flattened at the front, apparently that's a sign of a boy......

Top I'd say girl, Bottom boy.
Also basing that on skull shapes, the bottom looks similar to one of my sons scans
