Oh yeah, I love 3D scans, they are really amazing.  When we finally got to have one with the twins it was 3 days before I had them, they were in such a tangle in there that all we got to see was Ben's foot haaa, but it's a prized scan of that little foot let me tell you!  I really love the ultrasound images of my two in the womb together, after they were born we only manged to get a couple of them together and they aren't terribly flattering, but by far my favourite thing is the video we have of them in the womb, Ben is so alive, kicking and punching his way around the place...........he was so silent and still when he was born despite being alive so it's nice to think of him as that active little squidgy in my belly at times.
