Crawford Says "Hi, Dada"

This morning, mommy was holding Crawford after he had woken up from his nap. Daddy was coming around the corner and when he walked into the room, Crawford said so clearly, "Hi, dada!" And waved. Next thing he did was lean with his arms out to be held by his daddy. It was not only the first time that mommy and daddy have both heard him say dada at the same time but actually put two words together!
