Driving home from the library on Wednesday, Ellie said, "Oh no, where my sticker go?" Lulu immediately said, "Uh oh." It was so clear and so perfect, and her first official words! Of course, I said, "Lu, did you say 'uh oh'?" and she said it again. And Ellie and I were laughing and praising, and she said it again. So I whipped out my phone and captured it on video.
