A shopping thought - My saving grace when my wee girl became (on the basis of exposure to a single sippy cup) utterly obsessed with all things Disney princess, was the Princess and the Frog. Good New Orleans jazz, a story you're not horrified to expose your daughter to, and the ostensibly princess movie is actually all about frogs and alligators romping though a swamp - the gang of older brothers loved it as much as DD and her friends.
P.S. The first time DH had one-on-one time with 1 year old DD, they headed to the drug store, loaded up on nail polish and did a full manicure and pedicure. DH responded to my astonishment with "well - *someone* has to teach her to be a girl - and you don't know how!"
He still does her hair and nails - she's almost 8.
