Maternal nutrition, child nutrition, early sensory stimulation, and adequate nutrient intake throughout the life cycle are key factors that affect child development. Maternal and child malnutrition can lead to developmental delays, poor health outcomes, and increased disease risk for both mother and child. Early sensory stimulation through the five senses is vital for brain development and learning in infants and children. A variety of factors like culture, stress, illness, and sensory deprivation or overload can impact sensory stimulation and development.
