How does postnatal affect growth and development?

Postnatal factors significantly influence growth and development through nutrition, environment, and caregiving. Adequate nutrition, including breastfeeding and proper weaning, is crucial for physical growth and cognitive development. The quality of the home environment, including emotional support and stimulation, also plays a vital role in shaping a child's social and cognitive skills. Additionally, access to healthcare and early interventions can mitigate developmental delays and promote overall well-being.
