Littler has decided that she really is a dog, all day long every day. So the most common word she uses now, whether it serve as a verb, noun, adjective, pronoun, expletive, clause, diatribe, discourse, etc., is the word "wuhf." Thus:
"I want to play with [Little], wuhf."
"Daddy, Daddy, wuhf."
"I wuhf, I wuhf, I wuhf!"
"[whine, whine, whine] whuhf [whined]."
"Wuuuuuuhf!!" [meaning "I can't open the door"]
"Wuhf!" ["I did it!"]
Her stamina is remarkable, she's been doing it consistently for about 72 straight hours, and it took us about half that time to figure out what she was doing.
