I didn't know you could yodel!

Yesterday morning, Noah crawled into bed with us. We had some fun, giggly, family time, but the best part was this conversation:
Geary: Knock, knock!
Noah: Who's there!
Jeana: Little Old Lady
Noah: Oh! Come on in, little lady!
Jeana: No, say, "Little Old Lady, who?"
Noah: Okay, Who Little Lady!
Jeana and Geary: (giggles)
Noah (shrugs): Okay, see you later Old Lady...bye!
