Austin is clapping and waving, I have heard him say "hi" in his own baby way. We love our man and he loves us. I think he likes Millie the most though. He smiles all the time, but he doesn't really laugh. Millie is the only one that can get him going. Watch the clip below to see her in action. He also waves to Sherry in the end and says, "hi", but I was talking and I don't think you'll be able to hear it.
