Adoptive parents may be less likely to consider the possibility that they are doing something wrong, and blame the child's heredity. The parents may even unfavorably compare their adopted child with a near-perfect, genetically-related "fantasy" child. This enables them to blame ordinary problems which all parents face on their child's supposedly "defective" genes. Thus, while non-adoptive parents are focused on nurture, some adoptive parents are solely focused on nature (i.e. heredity) instead. This results in what could have been an easily resolved problem, going unresolved in families with adopted children, possibly accompanied by child abuse.
Closed adoption, not to be confused with sealed records, is an adoption in which the adoptive family and the birthmother never meet and know nothing or very little about one another. With the advent of open adoption, closed adoptions have become the exception in domestic adoption rather than the rule. The term closed adoption is most often used in relation to post-adoption contact, whereas the term sealed records is related to the access of legal documentation surrounding the birth and placement of the adopted child once the adoption is final. It is entirely possible to have a closed adoption and unsealed records or an open adoption with sealed records. The two practices are not mutually exclusive.
