"Tractor"

Aaron was playing today with one of Luke's John Deere tractors. As he was playing I kept asking him to say "tractor." It's not fully recognizable yet, but with gestures and toys to use as props you can tell he says tractor. Without props, it sounds like he's saying "dada/daddy." I also heard him say "moo" today in response to seeing a cow puppet on Baby Einstein -- which I've never heard before (though he may have said it lots of times before). :) Luke, Aaron, Zachariah and I were reading a Truck book on our new parachute (thanks Robin!) and Aaron attempted to say "truck" when asked.
