It doesn't just depend on genes. A child can become attached to the child's primary caregiver, but the primary caregiver does not have to be the parent. This attachment is represented in the relationships of children and their adoptive parents. Children will become attached to the primary caregiver, regardless of their parentage, if the latter is the source of protection and comfort. This attachment may be generated by the release of tension achieved through the soothing voice and touch of the primary caregiver and is not linked to the child's biology. If the child does not receive this type of attention, he may become detached and unable to form trusting bonds in his later years. In conclusion, John Bowlby's attachment theory reveals that a child will become attached to the caregiver primarily based on the care the child receives from the caregiver ( Berk, 2014). This attachment does not necessarily have to be the parent, but the person in the child's life who gives them the warmth and security they seek. This bond may change as the child grows, but the need for security will remain. In the event that a child does not have such a sense of security, they may suffer from maladaptive behavior in the way they engage in social situations later in life (Tayler, C., 2015 pp.
