"He looks cute! That's a nice outfit."
"No no no no no no no no no no no no..."
"That's cute! That's cute!" (as she goes through clothing on a rack at the store)
"I want to watch set treet (Sesame Street). I want to I want to I want to!!!"
"I don't want to watch the animals and I don't like the animals." (whine as I watch something other than Sesame Street)
"YOU do it." (when she wants to be a baby)
"I do it allll by myself!" (when she wants to be a big girl)
"One, two, three, four, five, sex, seven..." (I know it's just her pronunciation, but it still makes me laugh a little to hear her saying that word all the time in such an innocent way...)
