Kids who are hungry will eat. I never understood the whole tricking kids into eating anything like drenching stuff with salad dressing (even the no nutritional value iceberg lettuce). Yeah it sucks to hear kids whine. I know it does but honestly when it comes down to it I cook one meal and one meal only. Either they eat it or they don't. If they don't then they wait until the next meal of the day or snack time to get some food. End of story. Usually takes one or two times before they figure it out. But I will not cook two dinners because of whining children.
The only healthy benefit of milk is the calcium. If they're worried about the calcium intake of these kids there are other foods rich in calcium they could be feeding the children in addition to milk. It just blows my mind that they sugar up milk to essentially give kids calicum. Seriously. That's just sad.
