I have tried several times unsuccessfully to catch him saying it on video w/ Nana's camera. He is really close to saying Nana as well. So he offically has 2-3 words in his little vocabulary. Everyone keeps telling me that before long I will be pulling my hair out when all he says is "MaMa" all the time for every possible reason. Maybe so! But for now I am going to be proud that the Jack is becoming a big little boy!
