This is our first baby photo:

As you can see, the baby's still quite small. From the measurement taken of the top of the skull to the bottom (end of the spine) they estimated 14 weeks and 3 days, giving a due date in early December (11th?).
Now, I've never been able to see much in ultrasounds of babies on TV, but when you're actually there, and the foetus starts doing the macarena, it's pretty awesome - and pretty easy to see that it is a tiny little person. Some of the stills from the scan are reasonably clear though - like this one that shows the head, the spine, and one arm:

Anyways, I'm sure we'll take millions of photos of our kid, but there is no question that these are the first ones :)
