Self and other dialogue in infancy: normal versus compromised developmental pathways.

Dialogical Self Theory, co-regulation, and foundational movement analysis are used to present a description of the development of the dialogical self during the first five months of life using observations of two mother-infant dyads. Susan and her mother illustrate normative emergence of the dialogical self. Susan's I-positions emerge through positive interactions with her mother, for example, through body positioning and dialogue in a flexible yield-push pattern.
