Children’s health and human development includes more than just physical and physiological changes. Mental and emotional health and well-being are as important to a child’s development. Such factors as exposure to violence, parental occupation and stress, special health care needs, injuries, and exposure to illicit and prescription drugs can have long-lasting effects on children. Addressing the needs of children with or at-risk for mental or emotional health issues can help improve their quality of life through adolescence and adulthood.
