Underweight child
Parents might want to focus less on the scale and instead direct their energy toward providing their children with enough macronutrients (protein, carbohydrates and fats) and micronutrients (vitamins and minerals). Empty calories, like those in ice cream, might add a few pounds here and there, but they will not provide the nutrients a child needs to build a healthy brain, resilient organs and strong bones. So if you have an underweight child, begin by ensuring all calories ingested are nutrient-rich.
