All children need nutritious food. Assume no stereotypical preferences. If children request ethnic food or food preparation, such as seasonings, this should be provided to them. By honoring such requests, you help minimize the traumatic effects associated with uprooting a child.
Keep in mind that research has shown that food has significant effects on child's behaviors, cognitive development, and academic performance. Chose food carefully and wisely. For example, too much sweet in the evening, could be detrimental to the child's sleep pattern.
Withholding food will never be used as a disciplinary action.
