The u/s tech said he weighs approximately 10 ounces and that there was no doubt he was, in fact, a he. The measurements she took (head, arms, legs, stomach, etc.) are pretty much on par with my due date, give or take a day.
We got a DVD with some of the images she took (how times have changed-3 years ago at the same location we just got a couple printouts!).
Avery is very excited, as are we.
