Diego is now doing the elephant sound when he sees and elephant. He does the chicken (bok bok bok). He does the bees buzz. He meows. He beep-beeps and choo-choos. He tweets.
He said owl this morning.
He started saying mine last night.
He has also started telling me when he needs a new diaper. He'll point at his diaper and say, "I pee." or "I poop."
