here where I am it means you have a special bond or connection with someone...
a parent and child has a special bond (way of caring and loving each other)
the parent - child attachment is also called the first / original attachment because its the first kind of attachment a child experiences from the moment of their birth.
example whats the first thing to happen after a child is born? the child is handed over to the mother to hold on her chest, and breastfeed, care for
if you watch you tube videos you can see this special attachment in the way the parents look at their baby, hold their baby and how the baby quiets down, looks at the mother and relaxes, they feel safe, warm and loved by this person holding them.
having a healthy attachment means you have a special connection with another that is neither person controlling / abusing another, a sense of feeling you care about someone and you feel safe with them.
