Luckily since our initial terrible experience, we've had nothing but good ones with the US Consulate in Buenos Aires. So I'm hopeful that if we ever decide to move back to the USA, being married for 5 years and having a child will count in our favor and make the process much easier like it was for you.
As it is though, I've grown pretty comfortable here and don't know if we'll ever move back. All's well that ends well, I suppose. :)
