Step-by-step explanation:
Good nutrition during infancy is important for a baby's growth and development. A well-nourished infant typically triples their birth weight and doubles their birth length by their first birthday. It is important for infants to have a balanced diet that includes foods from all six basic nutrient groups. Breast milk is an excellent source of nutrition for newborns, as it contains nutrients for development and growth, as well as immunoglobulins to protect against infections.
