Attachment and Relationships
A child’s relationship with their caregiver—whether their parents, grandparents, or otherwise—is vital to their emotional and physical health. This relationship and attachment help the little one learn to trust others, manage emotions, and interact with the world around them.
When a child experiences a trauma that teaches them that they cannot trust or rely on that caregiver, however, they're likely to believe that the world around them is a scary place and all adults are dangerous—and that makes it incredibly difficult to form relationships throughout their childhood, including with peers their own age, and into the adult years.9
Children who struggle to maintain healthy attachments to caregivers are also likely to struggle with romantic relationships during adulthood. A 2008 Australian study of more than 21,000 child abuse survivors age 60 and older reported a higher rate of failed marriages and relationships.
