We present the patterns of organization that emerge from the developmental process of mother-infant communication in face-to-face exchanges. This process is conceived as creating a dynamic system in constant transformation and construction. The patterns of organization describe the periods of stability of this system, proposed by the EEA model as corresponding to three successive patterns, starting by an initial establishment, followed by a period of extension, and finally by an abbreviation of the dyadic exchanges. We analyzed the longitudinal mother-infant face-to-face exchanges from five dyads, describing the process of organization of these patterns. We identified a general tendency toward maintenance of the sequence of emergence and dominance of these three patterns in all five dyads, according to the proposals of the EEA model. However, each dyad differs in terms of age of appearance, dominance and duration of each of these patterns.
