Which milestone is associated with infants learning to recognize their caregivers?

The milestone associated with infants learning to recognize their caregivers falls under social development. This aspect of development involves how infants interact with others, form relationships, and understand social cues. Recognizing caregivers is a fundamental step in building trust and attachments, which are vital for healthy social interactions later in life. As infants engage with their caregivers and begin to distinguish familiar faces, they develop a sense of security and belonging, which forms the foundation for future social relationships.

While cognitive development does play a role in processing and remembering faces, the primary focus of recognizing caregivers is grounded in the social context of interactions. Physical development pertains to motor skills and bodily growth, while emotional development involves the regulation and expression of feelings. Thus, the milestone is most accurately categorized under social development due to its importance in establishing bonds and social connections with caregivers.
