Starting to read?

Ada loves books -- shocking! -- and has started to "read" to herself, which involves looking at the pictures and reciting stories she's memorized. Here she's telling herself about the story of Cinderella -- for some reason, a source of ENDLESS fascination. Why are girls obsessed with princesses? I certainly don't read the stories to her, at least not more than any other stories... and when I do, I try to convince her that it would be better to be the witch - at least she'd have some magical powers and could smite people instead of dealing with all the abuse that princesses tend to get before the prince swoops in and saves them.
