Kelli is a very picky eater, if she doesn't want something she'll nudge it away with her nose and then devour it the next day. One thing that we've found that she loves alot is carrots and green beans, more than any other veggie. We mash and mix a tiny bit with her food and she will eat it right up. Sometimes, if she's being particularly picky we'll feed her, which I know is bad but it gets her to eat and gets nutrients in her on the days that she's being stubborn.
Also, we never use canned veggies, only fresh or frozen. Cuts on the sodium. All veggies are boiled, too, with nothing added.
She could eat veggies all day long if we let her. We also do the boiled chicken breast, too. Mixing it with just a little bit of her food every now and then. We try not to deviate too much from what she normally eats, but these are tricks we use most of the time to get her to eat when she just won't.
