People always ask me what girls could pretend if they weren't playing princess. That lack of imagination saddens me. How about some historic American girls or women (preferably with cool costumes)? Of course, we don't learn much about them ourselves, so why don't you tell readers: who ELSE could our girls pretend to be besides a princess (preferably with a cool costume...)? How about Laura Ingalls?
This is the age of the internet--it's easy to educate yourself and expand your daughter's imagination.
And what could be more American than fighting for independence from (Disney) royalty?
"The history of the present King of Great Britain is a history of repeated injuries and usurpations, all having in direct object the establishment of an absolute tyranny over these states. To prove this, let facts be submitted to a candid world."
