That is REALLY interesting to me! We don't have kids yet (still debating, as I think you know), but one of the things I'm really big on is making sure any child of ours learns Spanish alongside English. I mean, we live in Florida -- this is IMPORTANT. The only problem is, both of us are quite rusty con la lengue de Espanol (I probably effed that up, even), so we need to get some fluency back before we can even talk about kids. Which is actually quite convenient when I find myself having to come up with reasons why we're not having babies already, because I can't tell you how often I hear (from strangers, never friends or fam) OMG WHY DON'T YOU HAVE KIDS ALREADY?
