I don't know if other parents do this. But occasionally Adam and I will talk to each other in a little high-pitched squeaky Lucy voice.

Most of the time we will have Lucy comment on her activities and her surroundings, and her plan to train a baby cadre and how she's enlisted the dog in the service of her secret plot to topple the Bighead world. (The personality we've given her is sort of a cross between Stewie on Family Guy and Diana Ross, pre-drunkening).

But occasionally, Adam will have her blurt out total nonsequiturs, many of them culled from 1980's television events. To wit, this morning he carried Lu over to the bed, and I said, "How are you, sweet one?" and he replied, as Lucy, "WHICH ONE OF YOU BITCHES IS MY MOTHER?"
