Lately Jonathan has taken to spouting nonsense words. I think he's just playing with sounds, having fun with it. It makes it a little trickier for me to know when I ought to be listening to him, though!
A few days ago he said something while we were driving in the car (not the easiest place to hear him). I turned off the a/c so I could hear better and asked "Jonathan, what did you say?" He thought for a minute and then said "Mommy, I'm just talking nonsense."
