Sitting in the bathroom, holding his R2D2 toy, and watching us give Little Miss her first bath:
"R2D2 doesn't think you guys know what you're doing."
Watching Little Miss eat:
"Look, she's eating you!" (Insert creepy, whispery voice.) "I'm going to eat you too!"
Eating dinner (baked nachos, for the record) himself:
"When I grow up, I'll like yucky dinner."
Shouted up the stairs to me as I was changing Little Miss's diaper:
"You'll never guess what happened in the dining room!"
Recalling the major events of the day to his dada:
"And Little Miss got out all of her poop!"
And, to end on a profound note:
"I really am growing up on you."
