China's one-child policy led to the abandonment of tens of thousands of infants. Included among these children were twins who were adopted and reared separately. Since 2006, 10 reunited twin sets participated in the first prospective study of twins reared apart. This exploratory study reports a qualitative analysis of the children's reactions to their first meeting with, and departure from, their co-twin. The majority of twins 18 months of age and older displayed strong attraction upon first meeting. Leave-taking included sadness, but responses varied across pairs. Theoretical interpretations of the findings and implications for parenting reared-apart adopted twins are provided. [ABSTRACT FROM AUTHOR]
