Abstract

Nutrition is fundamental to the physical growth, cognitive development, and immune competence of children. Optimal nutrition during infancy and childhood determines long-term health, academic potential, and adult productivity. This article explores the interrelation between nutrient intake and developmental milestones across different pediatric age groups. It discusses the impact of breastfeeding, complementary feeding, micronutrient supplementation, and dietary diversity. Emphasis is also placed on the consequences of malnutrition and overnutrition, the role of socioeconomic and environmental factors, and emerging nutritional strategies for promoting optimal child development.
