Ticka-Ticka-Ticka

What is "ticka-ticka-ticka"? It is what Sophia says if she is tickling you. She just started this week. It is pretty much what I say if I'm tickling her, so it's funny that she says exactly that. Lately she also seems to be saying things like "I did it" and "done" and "go-gee-go-gee-go-gee" which I have not figured out if it means anything (I don't think it does). We've also noticed her say "yeah" and "that" or "that one" in our question/answer conversations. She also nods "yes" or shakes her head "no" when answering our questions (and usually means what she says). Of course she also says hi and bye-bye when she is in the mood -- otherwise she just waves.

Sounds and words she says associated with animals: whispers "ki-ta" when she calls the cat, "og" for dog, "mmm" when she sees a cow, "ba" for the sound a sheep makes, moves her mouth like a fish... there are others that I can't think of now.

She might be saying a lot more, but we haven't deciphered all of it yet.

Words I've heard her say since I originally posted this: ball, baby (very clear!)
