Take a flip through Becky Bailey's Easy to Love, Difficult to Discipline. Very insightful! I think you'll find some great ideas in there. The woman is a genius. Also, Mary Sheedy Kurcinka wrote a fantastic book called Power Struggles that taught me how to deal with these kinds of things, and it's similarly incredibly insightful into the minds of children and how to work with where they're at, developmentally and temperamentally, to manage discipline challenges and to maximize teaching/personal growth opportunities (for me as much as my child, I think, LOL!). Both books are great this way.
By the way, spaghetti is probably on par with garlic bread, nutrition-wise :) Even the tomato sauce is super processed and over-cooked, killing most of the nutrients. As far as the food fights go, what I'd do is just serve only what I feel good about my child eating, rather than presenting foods in contrasts as "fun foods" and "boring/yucky foods." Otherwise, she'll get the message that healthy food is not as enjoyable as dessert or fun foods like garlic bread. ("You have to eat your _____ before you can eat your ______" tells them this rather point-blank.) I read about this in a parenting magazine, and thought it was brilliant. What they're saying is, it sets a kid up for unhealthy eating habits. And of course, by offering only healthy foods, no matter how much or how little they enjoy it, and how much or how little they eat of it, it's *all* healthy. Kids are a blank slate. For all they know, kidney beans are AWESOME! :D (And for all WE know, kidney beans ARE awesome! I even thought of this example because I ate a few kidney beans out of a can while making a recipe the other week, and thought, wow, yum, I could make a snack out of this all by itself...but all of these years I've been told that I can only get my snacking pleasure from Ding Dongs and Doritos.)
Speaking of healthy eating, one way to get your children to eat their *vegetables*, for example, is to serve casseroles or pasta salads, or soups and other things where lots of nutrient-dense vegetables are mixed in together, and flavored up fantastically. It's also important to highlight the veggies on the plate, making them the main attraction, rather than the obligatory healthy side item that is given hardly any attention on the stove (some overcooked corn, for example, or soggy broccoli from the frozen-foods section). This conveys a clear message to children: vegetables and healthy foods are boring and basically an afterthought. Sauce 'em up, make them fun, put them as the center attraction! This is in keeping with the food pyramid, too, in terms of portions. But it also tells your children that this is what Mom and Dad like best, this is what deserves dressing up, and so your children will automatically want it more (like wanting the toy that another kid has for no other reason than that the other kid has it).
Hope this regurgitated magazine article helps! Have fun with your little ones!
