My husband, CJ, is dying to know. He claims he'll be able to tell just by looking at the ultrasound. He's certain of this because he worked in research & development and used to test diesel cell engines where using a sonogram to detect cracks in diesel particular filters was his specialty. Uh-huh, and I suppose looking for a crack in an engine is much like looking for a penis on an embryo. This must be like how his growing up on a farm & helping calves come into the world will be such an asset to my birthing process. (See my Huffington Post article S#!T NEVER to Say to Your Pregnant Wife!)
My argument is this- even if he does find out the sex "on his own" how is he going to keep the secret?! There's no way he's not going to slip up. I'd slip up and I'm a master secret keeper.I can hear it already- we'll be in mid-conversation about the baby & he'll say "So, how is he- I mean- she feeling today?" Or on a random trip to Target and I start buying clothes or items that are not associated with the baby's gender I can hear him saying something nonchalantly like, "I wouldn't take those tags off if I were you." Or "I'd hang on to that receipt."
And that'll be great. Just great.
