Majority of children enter foster care due to abuse, neglect or other family problems. Children and youth in foster care come from diverse ethnic and cultural populations and are generally birth to 18 years of age (sometimes teens stay in foster care after their 18th birthday). They may have special medical, physical, developmental, psychological and emotional needs, low self-esteem, poor hygiene or poor academic performance.  The child or youth may belong to a sibling group or be an only child.
