Oscar's been saying Mom and Dada, albeit inconsistently, for weeks. And, as of last week, he had "uh-oh" nailed (commence throwing everything to the floor with force for the opportunity to say "uh-oh.")
But yesterday was the big one. The real first word. As we were coming down the stairs from his morning nap, he pointed at Nebo and said "dog" clear as a bell. Dog. He's said it five or six more times since then.
And so dog it is, Oscar's first official word.
