A children's hospital is a hospital which offers its services exclusively to children and adolescents. Most children's hospitals can serve children from birth up to the age of 18, or in some instances, children's hospitals' doctors may treat children until they finish high school. The number of children's hospitals proliferated in the 20th century, as pediatric medical and surgical specialties separated from internal medicine and adult surgical specialties.
Children's hospitals are characterized by greater attention to the psychosocial support of children and their families. Some children and young people have to spend relatively long periods in hospital, so having access to play and teaching staff can also be an important part of their care. With local partnerships this can include trips to local botanical gardens, zoo, and public libraries for instance.
