Comparing 3D sonos

So I have a 4 year old and when I was pregnant we did a 3D sono. I’m not pregnant with my 2nd and had a 3D sono this past week. I think they look alike but daddy doesn’t. What do you think? Has anyone had 3Ds done and they look the same then birth comes and they look alike or different.
