This doesn't work.
The grandparents will show them to her when you've trusted them to babysit. And your relatives will send Christmas gifts all wrapped up and when your little girl open's 'em -- yep: Disney products. And she'll see them at her friends' houses... she'll come home singing some crap song from Frozen over and over.
Her baby-sitter will buy her a Barbie. Women in lots of ads she sees will have their necks lengthend with photoshop. Her school will sell her princess books just like the ones they stock their library with. Costco will aim 90% of the female children's halloween costumes at the princess segment, half of those will be marked Disney. Your daughter will drag you back to the costumes over and over looking for Disney princesses she's seen and beggining you to buy one while you want to just get some cheese and get out.
Because it's not just your daughter who's the target of this long-necked, big-eyed, princess bullshit -- everyone is. And that's why you do get concerned about it, because it's not just Disney telling her to be a pricess, it's EVERYONE.
It's really frustrating having some stranger on the street tell your daughter she's a princess, but it happens all the time. I suspect it's not socially acceptable to snarl back "you calling her a parasite?"
At 4 or 5, she has all the time in the world to decide what she wants to do and be and plenty of time to change her mind about things, but this crap isn't going to stop when she's 10 or 15 or 30 or 60, and her whole life she will be judged and praised or criticized by a nation of people who are hit with the same propaganda.
