I don't expect my child to eat everything on his plate because I understand that we all have different dislikes and appetites. I do buy nutritious foods and put them on his (and my) plate with each meal. Some he likes, some he doesn't and some he eventually gains a taste for. My personal rule is that if you are still hungry, or hungry shortly after a meal, you may have some more of what was served, but not a fist full of cookies instead. I also try to cook meals that have some of what everybody likes...that way everyone has at least one thing one their plate that they consider a treat. Also, I have found that the example that my husband and I set for our son really makes a difference. If we go to McDonald's and order a BigMac and fries, that is a cue to my son that mom and dad know what is best for me so I should feast on similar stuff. When he sees us eat grilled meats, fresh fruits and veggies that he has already decided he likes (corn, carrots, green peas...) then he just kinda follows our lead. I also found a few years ago the he likes helping prepare the meals. I don't know how old your children are, but my son is 10 now and if I am grilling corn or steaming broccoli and carrots, he likes to chat with me and pull the silk off the corn while we are in the kitchen together. He also likes to measure stuff and mix ingredients, like if I am making a casserole or following a recipe. Good luck.
