"Bai-bee" (Barbie)

While visiting my sister's family in Washington, my three year old niece looks at me and says, "You is a bai-bee." I clarified by asking, "I am a baby?". She said, "No, you is a bai-bee." I look at her confused and said, "A barbie?" She said, "Yeah, you is a bai-bee". Her five year old sister quickly jumps in and said, "No, she not, she not made of plastic!"
