Potatoes V. Soup

My daughter won't eat potatoes. Mashed, baked, roasted, doesn't matter. She hears "potato" and automatically refuses. The kid doesn't even eat French fries. I mean, what kid doesn'tike a good French fry?!?  

The thing is... she used to love them. I'm not sure when this all started, but I know that it's all in her head. She's stubborn and defiant, and because I want her to eat potatoes on occasion, she won't. How do I know this, you ask?  Because my daughter loves soup. And not just any soup. You guessed it... Potato Soup. Of course, I didn't call it potato soup. It's just regular soup at our house. But she ate 3 bowls of it.
