@nroejb , I mean that's a fair inference, and if I were to be completely honest it was something I was sort of considering when I saw her throw that obnoxious fit in the very beginning when she couldn't find a single book to read. (Even though I knew logically that she was an adult, I thought something like; "Christ, she's reverted into the worst kind of kid. Reminds me of my brother catching a smack from my mom, when we were young.")
However, the author has done almost nothing to verify our speculation. And that's all we have. Speculation based on our presuppositions regarding neurological development in small children. I'm not an M.D. or anyone with either a Neuroscience background or a child psychology degree, so I can't really jump to the same conclusions as easily as you have. Rather, I see the emphasis on her knowledge and her business skills as signs of an un-reverted adult mind, that even scared her friend. That scene was actually one of my favorites, since it showed a.) an intelligent adult was lurking in there somewhere, and b.) behaving as herself rather than pantomiming the behaviors of an uneducated child had clear consequences.
