If it was behavior, that would be one thing. But it's entirely a food issue. My daughter will eat, but she asks for "snacks" exclusively. She will gladly eat: jello, popsicles, cookies, snack cakes, popcorn, chips, taffy, chocolate though not all kinds of chocolate, pudding, ice cream, coke, lollipops, pop tarts, fruit roll ups and variations of that, etc. She will eat as little as possible of meat, fruit and vegetables, even tho' we have talked about the need to eat different kinds of food to keep her body healthy. ("But a brownie IS different from fruit snacks!") So the usual method right now is, if she wants a snack she needs to eat a healthy food in order to get it. It's just like us adults having the self-discipline to eat dinner before desert, except small children don't have SELF-discipline so it needs to come from outside sources. A yogurt before animal crackers, some canned peaches and then a rice krispies bar. I don't feel bad about this. I do not use food to bribe her to behave well, nor do I withhold food to punish.
Jeanie, I just wish I had a tv in my bedroom. I was in hotel once ages ago with tv that had a timer, and that would be perfect. Imagine, set it for an hour and after you fall asleep it turns itself off. Maybe someday!
