Anyone else's LO suddenly become a picky eater?

Krista
My almost 11 month old went from eating anything you gave her to refusing to touch pretty much any veggies (even some fruits). Food that she loved before (carrots, peas, green beans, many more...) she won't even touch now. I've tried spoon feeding and leaving chunks in front of her and she acts disgusted & I know she likes them! 
Anyone else dealing with a picky eater all of the sudden?
I'm not sure how to handle it. Do I keep putting the things she's refusing in front of her and not give her things I know she'll eat? Or do I pretty much give up on the veggies for now and let her eat whatever she's willing to? I just don't know where the line between teaching her to listen to us and making sure she's eating enough is!
