How do you know if you are adopted?

Most adoptive parents now tell the child, or the adopted child was old enough to know he/she was adopted. You can talk to your parents about any questions related to your birth, place of birth, time of birth, Doctor Who delivered you, etc.

As a side note, many children wonder "Was I adopted?" Sometimes the question arises after a child meets a friend who was adopted, or when a child feels conflict with his/her parents. Some children wish they had been adopted.
