Yesterday I was driving in the car when the two girls got in an argument and began chanting back and forth at each other -- "Naughty Middle Girl" and "Naughty Toddler Girl." Eventually I had enough and told them to knock it off and that the word naughty was no longer to be spoken. Undeterred, the Toddler Girl said, "Okay. Stupid Middle Girl."

So, as the title says, her comprehension is excellent. I just wish her vocabulary weren't so highly developed.
