Did she say what I think she said?

Lil is babbling mostly breathy vowels sounds like oohh and awee and squealing I guess what they call cooing and she has been for awile now. But a couple times lately I have heard mmmmm and yesterday guess what she said....MAMA. I had to document it because I literally freaked out. She was looking at GayGay( my Mom) when she said it but....hey it's a start right?
