We had our ultrasound today. It's amazing what they can tell from those images...kidneys, all 4 chambers of the heart, the spine, different parts of the brain, the stomach, the diaphragm, etc. Based on everything the technician saw, our baby's anatomy is normal and healthy and he's right around the size he should be at this point. I'm so relieved to know he's doing well in there. And yes, it's a boy! I have to admit I was disappointed for a minute, but the more I think about having a boy, the more excited I get.
Here are some pictures of baby.
It's kind of hard to tell what you're looking at in these photos, but the first one is of the head and upper body, baby is laying face down with the head on the right.
This next one is one if his arm.

And this is the proof that it's a boy.

And here is the money shot.
