In virtually all cases, the decision is up to the adoptive parents regarding how to inform the child that he or she has been adopted, and at what age to do so, if at all. Although a non-profit adoption agency (if one is used) might mail newsletters and solicit funds from the parents, traditionally, it has been extremely rare for them to communicate directly with the child (usually, adoption agencies do not contain the word "adoption" in their name).
Now that the first open-adoption generation is under way, social workers are becoming more aware of the role of siblings in these arrangements. An adoptive child’s relationships with biological siblings need to be taken into account. And two children adopted into the same family may have different degrees of openness with their birth mothers. Openness may also affect decisions about family size.
It's equally important adopters understand that in a closed adoption little to no information will be exchanged with the birth parents, including their choice to arrange an adoption with the couple. This can feel like a distant business deal for some adoptive couples who want to know the nuances and personality of the mother of the child they're being placed with. Other adoptive parents may feel the separation of adoptive and birth parent eliminates possible instability an openly known birth mother's lifestyle may bring into a family dynamic. Also, in an open adoption, if communication is lost between the birth mother and adoptee, the child may become confused and hurt.
Most open adoptions lie somewhere in the middle, according to Grotevant and McRoy, exchanging letters, pictures, and phone calls, and having face-to-face meetings once or twice a year. Whatever their situation, many families report that relatives and friends condemn openness, and voice fears that the arrangement will make the birth parent want the child back.
