Living Tape Recorder

Okay...so I'm trying to get Madeline ready for bed and I'm explaining all that we're going to do (ie., read books, stop jumping on the bed, etc.) and she looks right up at me and asks, "What you talking about?" And from then on, everything we did she asked that same question. I can guess where she got that phrase from, but how is it that she is already so brilliant in her timing and delivery? I love this kid!
