At long last, pictures from our ultrasound! Our scanner isn't working for some reason, so I had to take pictures of the pictures, so they're not very clear, but hopefully you can see a little bit of him!
This is a 3D (4D?) picture with a pretty clear shot of his face! The thing on the right side is the placenta (he was using it like a pillow, so we couldn't see his whole face) and on the left is his arm. His eyes are closed and his mouth is open. I think he's a good sleeper like his sister :)
This is a more standard ultrasound picture, but really hard to see. It's a profile of his face. You can see his nose and mouth sticking up at the top and the umbilical cord in the background (it kind of looks like it's coming out of his mouth).

We were the last appointment on a Friday, so she was sort of rushing and we didn't get the most clear pictures we've ever seen, but I thought I'd post a couple. We also have a VERY clear shot of some boy bits, but I didn't think my son would want that aired, so just trust us, it's definitely a boy :)
