This study aimed to examine the process through which three student caregivers learned to develop relationships with a key infant in the context of an infant practicum course. The results revealed that the power and value of relationships were an essential context for learning about infant development, infant care and education, and preparation of infant professionals. As they developed reciprocal responsiveness with their key infants, the students shared that they experienced emotional rewards and intimate connections, and gained confidence in understanding and caring for infants. The results also highlight the importance of parent–caregiver relationships. The authors found that the caregivers benefitted from having opportunities to get to know their key infants’ families.
