Children born into a web of attuned relationships know how to join in conversations with new people and read social signals. They see the world as a welcoming place. Children born into a web of threatening relationships can be fearful, withdrawn, or overaggressive. They often perceive threats, even when none exist. They may not be able to read signals or have a sense of themselves as someone worth listening to.
