Guess who just admitted they have a case of baby fever? No, not me. Puh-lease. You all know that mine has been at a fevered pitch for like, oh I dunno, since the day I said “I do”. But when BEN halted his studying to show me a baby video of his cousin’s one year old baby dancing on those wobbly little baby legs to American Idol? Yeah…I’m no longer the only one with The (dreaded) Baby Fever in the Keno household!

Nearly every day that I after work I call my mom to chat about my day. I’m really lucky that we are so close. We started talking babies and she confessed that she had a bet going that I’d be knocked up before we end up moving back to eastern Washington and to the Palouse – where we call “home”. I don’t want to lose that bet and tell her that she’s probably right, like her mother’s intuition usually is. I guess Ben’s sudden interest in the Zillow app and hunting down the perfect house and property for us should have been a clue. But, apparently, I am really thick.

Did you ever hear about how we got engaged? Exhibit A.

Of course my first reaction was to question it, “You want to have babies with me?”.

His response, “I already told you once and I didn’t take it back.”.

Tre Romantique. *palm face*

Of course that ode to love was followed up with that ever loving smirk that he has that always renders me laughing helplessly.  Ben’s dry and sarcastic humor always gets me. I wouldn’t have it any other way.

So until we and Huck get our tiny human, we’ll keep dreaming and Zillow house hunting. We’ve got our eye on the prize and milestones to go before we get there, I mean c’mon. No babies until we hit up Europe next summer! So maybe I will beat my mom’s baby-bet yet.

Until then, I’ll keep my ovaries at bay.
