How do attachment relationships affect the ability of stepfamilies to bond?
People who have an insecure attachment history may have problems establishing close, loving bonds with new people. Fortunately, it is never too late to change this tendency. An insecurely attached child (or adult) can learn to trust others, and bond with people who treat him with consistent affection, attention, and respect. See Parenting & Attachment and Relationship Help: Building Great Relationships with Emotional Intelligence for suggestions on how to repair attachment problems.
