This paper consisted of a review of the most important theoretical views about the mother child relationship on the conceptual approaches and their possible effects on methodology. Empirical data resulted from research on the area have shown that: (1) the mother is an effective facilitator on a set of domains of infant's development, with focus on the "states organization", sensorial-perceptual capacities and cognition; (2) characteristics of infant and mother as interactive agents - mutuality - aiming to promote harmonic and synchronic relationship between the dyad are present on early social development.
