The document discusses attachment disorders and secure attachment in children. Secure attachment is formed through attuned interactions between caregiver and infant, which helps the infant feel safe and regulate their emotions and behaviors. Insecure attachment and attachment disorders can be caused by neglect, abuse, frequent caregiver changes and other traumatic experiences, and can impact brain development and lead to difficulties forming relationships and controlling emotions. Treatment focuses on forming a corrective attachment through structure, attunement, empathy, maintaining a positive effect, and supporting the development of reciprocity between child and caregiver.
