This article examines the emergent relationship between epistemic responsibility and frame awareness in early childhood, wherein a mother uses language socialization practices to guide her child into a new frame. The pair co-constructs the parameters of the new frame through negotiation of epistemic responsibility and remedial interchanges. The analysis demonstrates that these remedial interchanges arise from conflicting understandings of the embeddedness of frames and the epistemic dynamics that these frames entail. The child maintains epistemic primacy in her concurrent play frame, (...) which carries over to the recording activity given that the recording activity is embedded within her larger play frame. I argue that the data predict epistemic responsibility to be acquired earlier than the ability to shift epistemic dynamics outside of role-play. This study contributes to our understanding of frame and epistemic development in early childhood. (shrink)
