Ma!

So... I left for a few hours to get a haircut today. While I was gone, BJ watched McKay. When I arrived home and walked in the door, BJ and McKay were there to greet me. BJ said, "Who's home?" In response, McKay squealed in delight, "Ma!" I'm serious! It was as plain as day. BJ and I just looked at each other and then at McKay and all three of us started giggling. McKay seemed SO proud, and BJ and I were shocked and delighted. Crawling and now talking? What's next? (Please don't say walking.)
