A few days ago Jansen suddenly started laughing out loud in his highchair saying, "Pink truck! Pink truck!" He had a tone to his voice like, "Who would own a pink truck? I mean, can you imagine? A pink truck?!" We got him on tape saying it, but I think he is well aware of what we are doing and that we think it's funny because he got a little too into it. But you'll get the idea.
From Nate: I am proud to say that it was Jansen's own innate sense of coolness that told him that pink trucks are NOT acceptable. We did not teach him that--he came up with this little gig entirely on his own!! (we just "egged him on" so we could get it on film!)
