Children's brain growth, general health, and development are directly influenced by emotional relationships during early childhood. Contemporary American life challenges families' abilities to promote successful developmental outcomes and emotional health for their children. Pediatricians are positioned to serve as family advisors and community partners in supporting the well-being of children and families. This statement recommends opportunities for pediatricians to develop their expertise in assessing the strengths and stresses in families, in counseling families about strategies and resources, and in collaborating with others in their communities to support family relationships.
