This study captures the possibilities of infants' interactions in a Brazilian Early Childhood Education Centre. It contributes to an increasing number of educational research that is capturing the specificities of how young children use their understandings of context through gestures and verbal forms of language to create meanings as they develop social relationships with their peers and adults. The meanings of these interactions are explored based on the Vygotskyan notion of "perezhivanie." The research design was guided by ethnography in education principles. Participant researchers used fieldnotes and video recording to capture infants' interactions at the centre. For the purposes of this study, events were selected that related to the use of the cultural artefact pacifier. While teachers and families regarded the pacifier as an artefact that calms infants, helping them settle into a new environment, this study expands infants use of pacifiers as they also became artefacts to be explored and part of infants' social relations with each other. The events analysed highlight the biology/culture and emotion/cognition unities in infants' processes of development. This study argues for expanding teachers' practices in a process of appreciating what infants' intentions are and what they are communicating.
