Things Danielle does now..
She can sing "Twinkle, Twinkle, Little Star", "Teletubbies theme", "Row, Row, Row your boat."
When I am not agreeing with her, she says "Oh, Coming on now Momma" in a very cute tone of voice.
She says "Come on, Come on" and moves her arm to get me to follow her.
I am sure there are more, but those are the ones I can think of right now.
