My best friend called hers spawn as well, so that's probably where I got it from. We're all a bunch of nerds who are still surprised we're married, never mind creating little nerdlets.
I'm thrilled the doctor was willing to give me that one 3D shot, as generally they don't do them here unless you're high risk. I can vaguely remember back in 1985 hearing my youngest sister's heartbeat at one of Mom's ultrasounds, but couldn't figure out a thing on the tiny B&W monitor. I go to that same practice now, and they've got a giant full color flatscreen on the wall and the 3D thing.
