Think of her as someone just like you. She's a return to innocence and a retort to the over-sexulaisation of children. She's pro girl, she shows many different interests a girl her age can have without limitation, from ballet and horse riding to stargazing and fossil hunting.
She's not a slave to lurid pink and she isn't interested in being a mini-adult. She's like any 9 year old little girl - full of energy and jjoie de vivre.
