DaDa or TaTa?

Jackson uttered his first attempt at what Jarvis believes was da da today. Of course Jarvis was there to capture it knowing I would not believe him (listen to the commentary in the video). I honestly believe he was saying ta ta but I'll let you be the judge. Of course Jarvis does not believe me when I tell him that Jackson cannot distinguish yet what da da really means if he is in fact saying it. Now I must practice every day with him ma ma.:-)
