Another set of factors may be the cultural heritage of the couple or their expressed religious faith. If it closely matches the birth mother's values, the birth mother will know her child is being raised in a similar environment to her own. Language barriers may also be a reason why a birth mother chooses close to her own culture, plus the understanding that the child will have good roots in a family that can support it, but also roots in its ethnicity and people.
There are many ways a birth parent chooses the family for her baby. It is a long and involved process but one that can bring a sense of peace to the birth mother and the joy of a new child to adoptive couples. Establishing good, honest communication during the adoption process between the birth parent and the adoptive parents is a skill they will need to continue on with a process that can last a lifetime.
