I also buy the orange juice with calcium in it because my little weirdos do NOT like yogurt! So cheese and milk are the only dairy products I serve to them. They also don't like cottage cheese. I have picky eaters here, one won't eat veggies so I double her fruit, you just serve as balanced and healthy a diet as possible and if they are growing and thriving you are doing a good job. The parents are responsible for giving them nutrition too don't forget.
