chatttel
The correct answer is secure attachment.
According to the psychologist, Mary Ainsworth, infants and small children display either one of the three styles of attachment. These three styles are: secure attachment, insecure attachment, and avoidant attachment. Children who are securely attached to their parents, do not display much separation anxiety when they are away from their parents, are easily comforted by their parents, and that trust their parents will comfort them and provide for their needs and safety. Since baby Sophia has come to expect that her needs will be met, because of her parents' consistent warmth, responsiveness, and sensitivity to her, Sophia is on the path to develop a secure attachment with her parents.
