Both the caregiver and the child contribute to an attachment relationship. So a child’s attachment bond with her mother might be different than her relationship with her nanny or grandpa. The stability of these attachments can also vary within and across relationships. Some children have stability in their attachment over time. Other children undergo changes in the quality of their attachment. The stability of attachment depends on children’s security of attachment and quality of caregiving. It is also related to a child’s traits and family life, which we just discussed.

Children with more secure attachments as infants often have more secure relationships throughout life. Yet lasting changes in a family can affect stability.
