Nathan said bye bye to me today when Heather was leaving with him for daycare. He said it to Heather a while back but this is the first time he said it to me. He has also been waving periodically for a couple weeks but is just now getting consistent waving when you say bye bye and wave to him. This morning I was waving and saying bye bye and nathan was trying to mouth the words first and Heather asked what he was doing. I said he is trying to say bye bye and then he said it. It was pressious. Heather almost cried.
