Yep... his name is Oliver Grey. We call him Ollie. Ollie the Fetus.
I don't know that I could do "name at birth." Just the idea stresses me out. I suppose it's possible that he'll come out and look nothing like an Ollie at all... in which case we'll have to scramble for another name. I usually name things on impulse (I met my dog and knew her name immediately), but that seems funny when your saddling somebody with the name for a long, long time.
We seem to have a lot of green and blue. Which are colors we like anyway.
