The placement of older children can take two widely divergent paths. Generally speaking when a child has bonded to a birth parent then a need for an adoptive placement arises, it is usually critical for that child's emotional welfare to maintain ties with the birth parent. Sometimes a parent raised a child, but a problem has arisen, and parenting is no longer possible, and there are no family members able to take over the parenting role, so adoption is the best option.
Like any relationship, open adoption relationships evolve over time. Post-adoption contact may increase or decrease, or the nature of the contact may change along with people’s changing lives. However, even in the most open adoption relationship, the birth parent is not a co-parent but rather another very important person in the child’s life. The child’s adoptive parent(s) are his or her legal parent(s) and they have all rights and responsibility for the child. Most importantly, when birth parents and adoptive parents set out to forge their relationship, the child’s needs must always be paramount.
Historically, the four primary reasons for married couples to obtain a child via closed adoption have been (in no particular order) infertility, asexuality, having concern for a child's welfare (i.e. would not likely be adopted by others), and to ensure the sex of the child (a family with five girls and no boys, for example). In 1917, Minnesota was the first U.S. state to pass an adoption confidentiality and sealed records law. Within the next few decades, most United States states and Canadian provinces had a similar law. Usually, the reason for sealing records and carrying out closed adoptions is said to be to "protect" the adoptee and adoptive parents from disruption by the natural parents and in turn, to allow natural parents to make a new life.
Open adoption is a form of adoption in which the biological and adoptive families have access to varying degrees of each other's personal information and have an option of contact. While open adoption is a relatively new phenomenon in the west, it has been a traditional practice in many Asian societies, especially in South Asia, for many centuries. In Hindu society, for example, it is relatively common for a childless couple to adopt the second or later son of the husband's brother when the childless couple has limited hope of producing their own child.
