Well, I guess she's speaking

Here's the scene: C and I are at the breakfast table. I have a plate of pancakes, and C has both pancakes and banana on her plate. She turns to me and starts making the sign for more. I respond "more what? you already have both pancake and banana." C looks at her plate, looks at me, and then says:
"ssssssssssssssssrrrrrr- up"

"Do you want some syrup?"

"Yes" (accompanied by a head nod and a HUGE smile when I put some on her plate)

Bring back the milestone label. This girl is definitely talking.
