The most common caretaker in parenting is the father or mother, or both, biological parent(s) of the child in question, although a surrogate may be an older sibling, a step-parent, a grandparent, a legal guardian, aunt, uncle or other family member, or a family friend. Governments and society may also have a role in child-rearing. 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 skills vary, and a parent or surrogate with good parenting skills may be referred to as a "good parent".
