Open adoption is a term generally used to describe a variety of arrangements allowing for ongoing contact between members of the '
adoption triad' (adoptive family, birth family, and adopted child). The level of openness in any relationship varies widely. Degrees of open arrangements span from mediated contact, which implies letters and photographs sent through a third party (so that the adoptive family can maintain privacy), to full disclosure of the adoptive family's personal information. In fully open adoptions, there is actual physical contact, through meetings and visits between the birth family and the adptive family. Sometimes an adoption agency may describe an adoption as 'open' when the birth-mother (and/or birth-father) may have a say or may make the actual decision on who is chosen to parent their child, though this is not the generally accepted definition.
