This comment on the Special Issue contributions regarding the attachment network addresses the clinical implications of the findings from three perspectives: (1) the need to look beyond maternal influences on child developmental outcomes; (2) to be open to every seemingly peripheral influence on the child as this may have a central impact on the child, for example, grandmothers, the parental couple relationship, and others not living in the child's home but nonetheless influential; and (3) identify and cultivate security spreading effects that help change not only the child, but the child's relationships with others in and outside the family—to the benefit of all. Some evidence‐based attachment‐based interventions are highlighted.
