We were able to see her suck her thumb, stick her fingers up her nose (or at least that's what it looked like), hide her face, and "box." Here's her fists up in front of her face (which you can't see), like a boxer. The black hole under her fists is her heart.
Then we saw toes. If you can make it out, foot on the left is her left foot; hence the modesty (crossed legs) that prevented us from seeing if she was a boy or girl for quite some time. She appears to have all her fingers and toes.
This is her spine. I think it's creepy looking. Her bum is to the left, she has a very little butt like Ryan. Her arms and legs are curled underneath; she's literally in the fetal position. Her head's partially cut off, but it's to the right.
Shawn kept checking for girl/boy parts in between various measurements. Towards the end, she opened her legs JUST enough to see something. You can see her thighs are still pretty close together. In the end, she flashed us a few times for Shawn to be confident of the sex.
Here's a picture of her legs, crossed and locked. (Let's hope this is a good indicator of what she'll be like with the boys.) You can see her knobby knees, calves, and a foot. This is the position she kept her lower body in for most of the scan, despite all the orange juice I drank beforehand.
So that's that. Mystery solved, we're having a girl. Oh and she's currently 9 ounces, give or take a little. The entire time, she was laying horizontally in my belly. We had to poke her around a lot to get some of these shots.
