The full ultrasound took about 45 minutes for the twins and allowed us to see each body part of both Baby A and Baby B. Except for their sex organs, which we reminded both the doctor and nurse that we did want to know. The full ultrasound provided us the reassuring news that each baby appears to be perfectly healthy and is growing well.

The image above isn't real clear, but was the only photo of the two together that we were able to take home. That's Baby A on the right and Baby B on the left, separated by a very thin membrane (which we enhanced with a white line--the real membrane is too tough to see when we reduced the photo to put online).

The fact that the twins have a thin membrane separating them and that there is just one placenta (according to the doctor) doesn't tell us anything about their zygosity (whether they are identical or fraternal). Our doctor said she could have told us if they were the same sex or different sexes, but we told her we didn't want to know yet.

Here's what we did find out. Baby B is slighly bigger at this point, weighing 15 ounces, while Baby A checked in at 13 ounces. Those are both good weights at this stage (21 weeks) of the pregnancy. They both have the same amniotic fluid level, another good sign. Each organ they looked at (heart, liver, kidneys, brain, etc.) looked great. And they were both very active!

One of the really neat things about the ultrasound is you get to take home a videotape of all the action. The twins will probably want to watch the latest Disney movie first, but one day we hope to all watch their first home movie together...
