Duh...

Tonight at dinner:

CC- Night night! (She knows it's time for bed after we eat- we've trained her well:)

Tony-yes CC is going night night.

me- She can say banana now Tony. CC say banana.

CC-banana

me-that sounds an awful lot like night night- think she knows the difference?

Tony-is CC going banana?

CC-(as clear as a bell and with an incredulous look on her face) No, night night.
