Characteristics of a Healthy Open Adoption Since the 1980s, open adoption has been benefiting adopted children, their adoptive families, and their birth families. These adoptions, in which the birth family and adoptive family exchange information and remain in contact with each other, are now the norm, with more than 90 percent of domestic adoptions consisting of some degree of openness. When an open adoption relationship is healthy, it provides everyone involved with a more informed, supportive, and encouraging adoption experience. While open adoptions can vary widely, there are certain characteristics that define every healthy open adoption.
