My five year old has been a puker from day 1.

She is not a meat eater, aside from some fish. She loves fruits and veggies. But the problem is, if she doesn't like it, she will gag and throw up. Her doctor doesn't seem concerned about it, but it makes mealtime a headache. I always make at least one thing she likes, so she'll at least eat that.

Any suggestions for what to do for her? Will she grow out of it? Could she be doing it on purpose? She seems awfully sensitive to smells. Could that be the issue?
