At some point in the last month or two, Lillian has begun to apply the words “poo-poo” for comic effect. This turns ordinary words into uproariously funny ones. So, if you say: “Lillian, it’s time to put on your shoes,” she might respond “I’ll put on my poo-poo shoes,” followed by several minutes of uncontrolled laughter.
I suspect the influence of some of her peers; I imagine there is an unending line of slightly older four-year olds transmitting to slightly younger ones the joys of potty humor—a line that stretches back many thousands of years—a line of transmission in which my own four-year old self undoubtedly played a part long ago.
In the picture above, Lillian has used her magic wand to turn her grandfather from a poo-poo head into a poo-poo frog. She is most pleased with herself.
