Occasionally birth parents experiencing shame or sadness just have to retreat for a while. In rare cases, when safety is an issue, adoptive families may have to cut off contact. A child whose biological parent disappears experiences a double whammy. He wonders why he was placed to begin with, then feels rejected again because a birth mother no longer visits.
Although open adoptions are thought to be a relatively new phenomenon, most adoptions in the United States until the twentieth century were open. Until the 1930s, most adoptive parents and biological parents had contact at least during the adoption process. In many cases, adoption was seen as a social support: young children were adopted out not only to help their parents (by reducing the number of children they had to support) but also to help another family by providing an apprentice.
In all adoption searches, it is uncommon to find both the birth mother and father at the same time. A separate search, if desired, can be done afterwards for the father. Since males seldom change their surnames, and the mother might have additional information, it is usually easier than the initial search for the birth mother. In many cases, adoptees are able to do this second search for their birth father by themselves (or they try before paying for assistance).
