How do you develop an infant with a sense of secure attachment and what are the differences between an infant/child with secure attachment to one with an
insecure attachment?

You can develop a secure attachment with your baby through nonverbal emotional interactions such as reassuring touches, attentive eye contact, and a warm, affectionate tone of voice.

One of the most important—and, to some ways of thinking, paradoxical—findings was that a secure attachment early in life led to greater independence later, whereas an insecure attachment led to a child being more dependent later in life.
