Which factors are essential for supporting normal child growth?

The choice highlighting good nutrition, sleep, and exercise is fundamental to supporting normal child growth because these elements directly affect a child’s physical and developmental health. Adequate nutrition provides the essential vitamins and minerals required for growth and brain development, while sufficient sleep is crucial for cognitive development and physical health, allowing the body to recover and grow effectively. Regular physical activity is important as it not only strengthens the body and bones but also contributes to emotional and social development. Together, these factors help ensure that children grow at a healthy rate and develop the necessary skills for daily life.

In contrast, while stress management and family interaction play vital roles in a child's emotional and social well-being, they do not directly address the physical aspects of growth like nutrition and exercise. Options involving limiting screen time can be beneficial for maintaining a balanced lifestyle but do not contribute to growth in the same concrete manner as nutrition, sleep, and exercise. Regular testing and evaluations may monitor growth and development but do not influence growth directly like the biological needs provided by nutrition, rest, and physical activity.
