Jack speaks!

Tonight as Stephen was putting Baby Man to sleep, Jack said his first sentence... (or so Stephen says). Here's the scenario. He got a bath, was put in his jammies and sleep sack... and Stephen was giving him a bottle and rocking him in the chair. I went downstairs... and I heard Jack crying. So I went over to the monitor and turned it on so I could listen. I heard Stephen ask me to come upstairs... so I did. I got up there and Stephen said with absolute certainty that Jack had just said his first sentence. The sentence was: "I want my Mama." No ifs and or buts about it, Stephen insists that is what Jack said. He may be possibly the smartest 9 month old on the planet. What do you think?
