Her in-game/world age at this point is given as eight years.I get she looks like she's five years old,
On the one hand, she has tried to conceal her nature. On the other hand, she is in the body of an eight-year-old girl. This physiologic change would definitely have psychologic consequences. She has much of her previous set of memories, but may have lost some of the previous deep structure; her brain is developing now as that of an eight-year-old (albeit with a surprising body of knowledge), and she is hormonally different.but in her previous life she was, or was close to being, an adult: does she have to act like a kid?
