Shmokes, you DID try violently shaking her to straighten her out, right? 
Mebbe a swat on the nose with a rolled-up newspaper?
Ugh . . . I wish, for once, you could be helpful. I'm not retarded. Those were the methods of first resort. The choo choo train wasn't even attempted until the shaking and smacking proved ineffective.
It's been 16 years since I had to deal with this. That was about as helpful as I could be, since we just beat the kids into submission, at which point they were going to eat whatever was put in front of them just to stop the beatings. And NO, my kids did NOT get fat from eating Friskies, PLUS it was easier to buy the biggest bag to save money.
Enjoy this time while you can. Mine are 16, 17, & 18. They're like goats now, and I'm surprised they even bother opening a can or bag instead of just eating the whole thing. In fact, we count on the bags being a source of fiber for them so that we can chalk up another point in the "We're a good parent" column.
You'll be surprised at how your child will learn to manipulate you into doing if you worry so much about stuff like this. Well, MAYBE you'll be surprised. Me, I'll just sit back and enjoy hearing about all the different "struggles" we go through as parents - some of them, our own fault.
You and the missus are doing FINE as parents, I'm sure of it. Count yourself lucky if this is the biggest problem you have with her. And don't forget, a shaking is fine to keep the kids in line
