Parents need to know that while this site provides fun games for younger girls about fashion and such, it's run by Mattel and there are plenty of areas for product promotion. On every page there's a link to shopping pages and things to buy. Let your kids log on, and you can bet you'll be hit up for a Barbie or Polly Pocket doll.
My daughter has been playing on this site since she was 5. It is by no means educational, but it links to Barbie, Polly Pocket, MyScene and others. It is fun for little girls to take their online firnds for make-overs, give manicures, and decorate rooms.
There is definitly a 'buy this' on every page, so make sure you talk to your girl about advertisements before free-play.
