In the context of infant nutrition, it’s essential to understand that infants experience rapid growth, particularly in the first year of life. During this phase, their energy needs are significantly higher relative to body weight compared to adults. Breast milk is the ideal food that meets an infant's nutrient requirements for the first six months, followed by complementary feeding starting from six months. Key nutrients for infants include protein for muscle growth, calcium for bone health, iron for blood expansion, and numerous vitamins (e.g., Vitamin A, B12). Sustainability of maternal health directly influences the infant’s well-being; thus, mothers must maintain a nutrient-rich diet to support healthy breast milk production. Furthermore, hygiene during complementary feeding is pivotal to preventing infections. Providing the right nutrients during this critical stage helps avoid long-term health issues and enhances overall quality of life for infants.
