Parents with an adopted child wonder, when and how to tell their child that he or she is adopted. They also want to know if there are special problems for an adopted child.Child and adolescent psychiatrists (精神病学家) recommend that the child be told about the adoption by the adoptive parents. Children should be told about their adoption in a way that they can understand.There are two different views on when a child should be told about the adoption. Many experts believe the child should be told at earliest age possible. This approach provides the child an early opportunity to accept and integrate the concept of being "adopted". Other experts believe that telling a child too early may confuse the young child who can’t really understand the event. These experts advise waiting until the child is older.In either case, children should learn of their adoption from the adoptive parents. This helps give the message that adoption is good and that the child can trust the parents. If the child first learns about the adoption intentionally or accidentally from someone other than parents, the child may feel angry and mistrust towards the parents, and may view the adoption as bad or shameful because it was kept a secret.Adopted children will want to talk about adoption and parents should encourage this process.

A. be told the truth once he or she is adopted
B. be informed of the fact that he or she is adopted as early as possible
C. be told the truth by the adoptive parents themselves
D. always be kept in the dark about the fact through channels other than the adoptive parents.
