Parenting or child rearing promotes and supports the physical, cognitive, social, emotional, and educational development from infancy to adulthood. Parenting refers to the intricacies of raising a child and not exclusively for a biological relationship. The most common caretakers in parenting are the biological parents of the child in question. However, a caretaker may be an older sibling, step-parent, grandparent, legal guardian, aunt, uncle, other family members, or a family friend. Governments and society may also have a role in child-rearing or upbringing. In many cases, orphaned or abandoned children receive parental care from non-parent or non-blood relations. Others may be adopted, raised in foster care, or placed in an orphanage. Parenting styles vary by historical period, culture, social class, personal preferences, and other social factors. There is not necessarily a single 'correct' parenting style for raising a child, since parenting styles can affect children differently depending on their circumstances and temperament. Additionally, research supports that parental history, both in terms of their own attachments and parental psychopathology, particularly in the wake of adverse experiences, can strongly influence parental sensitivity and child outcomes. Parenting may have long-term impacts on adoptive children as well, as recent research has shown that warm adoptive parenting is associated with reduced internalizing and externalizing problems of the adoptive children over time.
