Does this count as her first word?

Saturday night, I was changing Diana - and she was talking up a storm!  Just making noises, being cute...so, after I got her redressed, I decided to roll a little video so I could show Steven later that night.

Then, it sounded like she said her first word....

Does that count?  Did she say what I think she did??  Steven is pretty psyched.  Now, we haven't been able to replicate the moment...but he is claiming dibs on her first word!
