Imagine him or her running for congress. Or applying to law school. Or being called over the high school loudspeaker for scoring a goal in a soccer game--- think of the reactions she'll receive. Think of the mean girls in middle school and how they'll react.
And, as hard as it may be to believe, she may grow up to be one of those people who just don't love Disney, and she'll be stuck with a name that doesn't reflect her.
I would seriously rethink the name.
