Cole said Bye-Bye and waved tonight!

I was going out of the room where Russell & Luke were and I heard him say it real softly. I practiced and kept trying to ge thim to say it. I went back in there and FINALLY we got him to do it. He kept doing it as I was walking off and they could not hear him, they could just see him waving. But after a few times he said it where they both heard him too! Are yall saying "Awwwwwwwwww" like I am? HA! :)
