This theory is supported in another more qualitative study wherein adoptive relationships marked by sameness in likes, personality, and appearance, were associated with both adult adoptees and adoptive parents report being happier with the adoption.Other studies provide evidence that adoptive relationships can form along other lines. A study evaluating the level of parental investment indicates strength in adoptive families, suggesting that parents who adopt invest more time in their children than other parents, and concludes "...adoptive parents enrich their childrens lives to compensate for the lack of biological ties and the extra challenges of adoption." Another recent study found that adoptive families invested more heavily in their adopted children, for example, by providing further education and financial support. Noting that adoptees seemed to be more likely to experience problems such as drug addiction, the study speculated that adoptive parents might invest more in adoptees not because they favor them, but because they are more likely than genetic children to need the help.Psychologists findings regarding the importance of early mother-infant bonding created some concern about whether parents who adopt older infants or toddlers after birth have missed some crucial period for the childs development. However, research on The Mental and Social Life of Babies suggested that the "parent-infant system", rather than a bond between biologically related individuals, is an evolved fit between innate behavior patterns of all human infants and equally evolved responses of human adults to those infant behaviors.
Jasmine Whitbread, chief executive of Save the Children said: "The vast majority of the children currently on their own still have family members alive who will be desperate to be reunited with them and will be able to care for them with the right support. Taking children out of the country would permanently separate thousands of children from their families—a separation that would compound the acute trauma they are already suffering and inflict long-term damage on their chances of recovery." Rehoming in the United States
With the increase in adoption rates over the many decades, the United States has been faced with a new morally questionable practice: rehoming. This is the act of caregivers posting an advertisement when they do not feel the child should be in their care any longer. Investigation of the childs new housing situation is not required in this practice, and this has created an underground market, one where child traffickers can thrive. There is a lack of regulation surrounding this practice and current legislation contradicts each other, making this harder to combat. When a parent adopts a child, they may not have been aware that the child has special needs and thus, are not equipped to help this child. The child may act out or not fit in with the family so the family turns to rehoming. Rehoming is not adoption and because of that, the government does not have to be notified and adoption agencies are not involved. Thus, re-homing is a prime target for child and sex traffickers.
