It’s important to keep in mind that, while adoption relationships can change, it is more complicated to increase contact than to decrease it. If a birth mother starts with an open relationship and then decides later that she needs distance, she can do this at any time. However, if an adoption is closed and a birth mother wants more contact, then she has to come to an agreement with the adoptive family. Therefore, it is especially important that a birth mother choosing closed adoption is sure that it is what she wants.
In a confidential adoption, neither the adopter nor the birthparents know each other, nor do they ever meet. Instead, all the arrangements and paperwork occur through a middleman, usually an adoption agency or an attorney. Some people call this a closed adoption, although I prefer the terms confidential and traditional because they sound nonjudgmental. A confidential adoption doesn't mean that the adopters and birthparents know nothing about each other. What it means is they have no identifying information about each other.
Decades ago, virtually all adoptions were closed. A closed adoption means that there is no contact whatsoever between the birthparents and the adoptive parents and child after the adoption takes place. In fact, there may also be no contact before the adoption. Nowadays, however, the trend in the United States is toward open adoptions, in which all the parties to an adoption meet and often remain in each other's lives.
Even if you are not sure whether an open adoption is right for you, most birth and adoptive parents find that speaking and meeting with one another before making a commitment, helps them to decide whether to move forward with an adoption plan. Meeting in person allows the birth and adoptive parents to get to know one another and often provides the birth parent(s) with the confidence of knowing that they have selected the best family for their child. Many birth parents who have ongoing contact with the adoptive family find that receiving information about the child, and knowing that the child is thriving, helps to ease their feelings of loss. Children who are in direct communication with their birth family may come to understand that their birth parent didn’t abandon them but made the decision to place them for adoption out of love for them. Many adopted children also benefit from having a direct connection with another person with whom they have a shared biology. The benefit for adopted persons to obtain updated medical information from genetically related family members is also undeniable. While some adoptive parents fear that an open adoption will confuse their child, ongoing research has not born out that concern.
The social stigma of unmarried mothers, particularly during the Baby Scoop Era (1945-1975) rendered them social outcasts. By the 1980s the situation improved greatly and the vast majority of unwed mothers kept their babies. In a mother driven society after WWII infertile couples were also seen as deviant due to their inability to bear children. The social experiment of taking the children from "unmarried mothers" and "giving them" to adoptive parents became the norm during the BSE. These adoptions were predominantly closed. The records were sealed, biological mothers were told to keep their child a secret, and adoptive parents told to treat the child "as if born to".
There are also private search companies and investigators who charge fees to do a search for or assist adoptees and birth mothers and fathers locate each other, as well as to help other types of people searching. These services typically cost much more, but like search organizations and search angels, have far greater flexibility in regards to releasing information, and typically provide their own intermediary services. However, they may not circumvent the law regarding the confidentiality process.
