A child aged 2-3 years should have a serving size of what fraction compared to an adult's serving?

The correct fraction for a child's serving size compared to an adult's serving is 1/4. This guideline is based on the understanding that children's nutritional needs differ significantly from those of adults, reflecting their smaller body size and unique growth requirements.

At ages 2-3 years, children are in a critical stage of growth and development, but their caloric and nutritional demands are not as high as those of adults. Therefore, serving sizes are generally scaled down to accommodate their smaller stomach capacity and lower energy needs.

Using 1/4 as a serving size fraction aligns with dietary recommendations and helps ensure that children receive appropriate portions without overwhelming them with food. This enables them to learn about healthy eating habits while preventing overeating.

The other options suggest larger servings that do not appropriately correspond to the nutritional needs and eating capabilities of young children.
