She talks a lot, though it's usually really hard to understand her. She knows exactly what she is saying, though, and gets frustrated with us for not getting her meaning, when it's clear as crystal to her that "Na Ba Ta! NA BA TA! NAAAABAAAAATAAAAA!!!!" means "clementine". But we're learning, and so is she.
And her little, "Uhyootooooo!" after an "I love you" makes it all worth it.
