What is the basic nutritional need for a 6-8 month old baby?

During the 6-8 month stage of an infant's development, their primary nutritional need is met through breast milk or formula. At this age, babies still rely heavily on these liquids for their nutritional intake. Breast milk or formula provides the essential nutrients, vitamins, and minerals necessary for healthy growth and development.

While some introduction to solid foods can occur at this age, it is not the primary source of nutrition yet. The emphasis on breast milk or formula ensures that the baby's requirements for calories and hydration are adequately met, as they continue to grow rapidly.

The other options suggest varying degrees of solid food intake or specific servings of certain food groups, which are simply not the main nutritional focus for infants in this age range. Solid foods can be introduced gradually, but they are supplementary to the main source of nutrition, which remains breast milk or formula.
