lol sometimes its just pushing them to eat what they dont like, my brother inlaw pushes his kids [my niece and mephew] to eat whatever they whine and say 'i dont like that!' and when their finished they say, wow that was yummy!
my mom used to make us cabbage soup and there were tons of veggies, and i remember loving it when she made it, because it didnt have that vegetable taste to it, it tasted more like the tomatoe broth that you can make it in.
also, im not sure where you live, but where im from-canada-we have this thing called Greens Plus, and they have a Kids Greens Plus, and one dose of this stuff is equal to one days serving of fruits and veggies i think, its a liquid, and my brother inlaw mixes it in with some juice like orange juice, or pomegranet, cranberry, blueberry tropicana juice, so they dont taste the bitterness.
that could be a suggestion if she is still being fussy with veggies, to insure she is not missing what she needs.
