What behavior indicates an infant's desire for closeness to an attachment figure?

Crying when separated is a clear indicator of an infant's desire for closeness to an attachment figure. This behavior reflects the emotional bond that the infant has formed with the caregiver, showing that they are distressed when that bond is disrupted. Infants communicate their needs primarily through crying, and when they cry upon separation, it signals their discomfort and longing for the presence and comfort of their attachment figure. This response showcases a healthy attachment relationship, as the infant feels secure and connected to the caregiver.

In contrast, behaviors such as sleeping or playing independently might not necessarily indicate a desire for closeness. Sleeping can occur for a variety of reasons, including tiredness or a sense of security in their environment, while playing independently can suggest that the infant feels safe and comfortable exploring their surroundings, thus not needing immediate closeness. Ignoring the attachment figure indicates a lack of interest or emotional connection and does not reflect the desire for closeness.
