Figuring out this toddler language

I am a true believer that I am multi-lingual. I do know a tiny bit of spanish but I am nowhere near fluent. I do, however, count myself among the few that are able to speak their toddler's language. I can't explain the empowerment I feel when I finally figure out one of my sons' words. I can only compare it to watching the spanish speaking soap operas on tv and feeling great about comprehending one of the 5000 words they say per minute. On this note, I just figured out yesterday that when Jack says, "What somebody overthere doing?" He is asking Who that person is. Fantastic. Now on to Brady...this might take me awhile ;)
