An estimated 63% of the population have a healthy, secure attachment style.

Morehead said the security usually stems from having a healthy relationship with parents, where they were allowed to go out and explore the world as children, but also felt safe and protected.

These children had their needs met, and their parents "delighted in the need."

"A baby cries because they're hungry, thirsty, wet, whatever, and a parent meets that need and is happy to meet that need," she said. "There's not a coldness about meeting that need, and children then learn that caregivers can provide them comfort and support and that people are good."
