Most folks are best served having a gun that is not trigger pull ready. Life comes at you fast as the commercial says. I once nearly shot my ceiling because of a bad dream. Personally I have no problems with a loaded gun but I do not have any gun condition one unless it is in my direct control. Maybe a quick access safe, or at least condition III. It won't be long before those cute kids touch things they shouldn't, prepare your habits now.
Just a quick read of this thread gave me annoyed vibes. You sound about as inexperienced as your wife, so why not make getting trained a job of equals? She's not some pretty little lady who needs your protection, she is a mother and human with just as much on the line as you. For all we know she is on prettypinkguns.com right now posting about how to best protect her fragile husband.
Probably just a byproduct of too many what guns for the little lady threads, but seriously, let her make her decisions and approach it together, don't propose to be the authority when you aren't. Get thee to a trainer, one that treats women like adults. And have fun at the range together, a pleasure long denied me, none of my female acquaintances liked guns thus far.
