In a Brazilian urban context, Seidl de Moura, Ribas, Seabra, et al (2004 and 2008), the behaviors had examined the characteristics of the interactions of the mothers with its babies analyzing. A set of common activities as partners in social exchanges was identified and some of the characteristics of the initial interactions had been analyzed. The episodes of interaction of the type face-the-face predominated, if mainly characterizing for the activities to touch, to look at and suck. The predominant activities of the mothers had been: to look at the baby (99.2%) and to touch the baby> (83.4%). Moreover, one observed some moments of interaction through the stimulation for objects, as well as affective interactions through the corporal contact. These findings suggest the importance of the activities of looking at and touching in the interacional process mother-baby, strengthening the importance of the affectivity as constructive in these interactions and basic for the infantile development. Thus the quo is seen positive is for the baby the possibility of affective exchanges and corporal with the mother and the significant quo it can be the lack of this for institutionalized babies who do not possess this contact. Of the point of view of the global development of the child, one perceives that the affective relations between mother and baby had gained prominence and exist some authors who if had dedicated to the study of the relation mother-baby.
The first research that they aimed at to understand of deeper form the binomial mother-son had had origin after the ending of World War II. At this moment, the children orphans, or the abandoned ones for the mothers, had been used as study object. At the time, it was verified that the absence materna provoked riots in diverse areas of the life of the child. Working in an orphanage close of the United States, Spitz (1958) observed that the babies who were fed and dresses, but almost did not receive affection, nor were insured in the col or packed, presented a syndrome that it called of hospitalismo.
