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.
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.
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).
