What will be an ideal response?
Providing an infant with a healthy diet and opportunities to explore the world will support the development of brain cells, a process that is governed by genes. Brain development, in turn, influences motor development, further supporting the infant's exploration of the physical and social world, thereby promoting cognitive and social development. Active engagement in the world encourages connections among brain cells. In this way, brain development, like all other aspects of development, is influenced by dynamic interactions between biological and environmental factors.
