How secure sibling attachments happen
The importance of a secure parent-child attachment is not a new revelation: This is what sets the foundation for all future relationships a child will have in his or her life. But there is also something to be said for security between siblings. A connected relationship between brothers and sisters also provides a foundational context: It is an opportunity to develop the groundwork for peer relationships in a child's life.
API Leader, Certified Positive Discipline Educator, author and mother of 2, Kelly Bartlett explains the developmental process of secure attachment among siblings on API's online magazine, The Attached Family.
