"I'm ... earning ... matching earrings!"
Sure, it's just a movie, but it's a movie about a whore. Even if she has a heart of gold and all her own teeth, she is someone who porks strangers for cash, and that's the kind of thing your kid should wait to experience, at least until she can properly pronounce her Rs so the word comes out as "whore" instead of "ho-wah."
After the non-insane world erupted in an uproar over this, the little girl's mom was apologetic and promised to use more sense when making decisions about her child from then on. Just kidding -- of course that never happened. Instead, her mom is proud of her choice and all the media attention it garnered for her li'l victim because, as you'll notice, most if not all of these parents seem functionally incapable of actually caring for their children, as opposed to using and exploiting them for whatever it is they get from competing in pageants, whether it be money or notoriety or a chance to be mocked mercilessly by online comedians.
