The full development of a baby alone will be able to occur to count itself on the love of its parents, that it is the expression of the close relation of what the scholars call of attachment. The authors show that he has different forms of attachment, established since the beginning of the relation between the mother and the baby. Mitchell Blutt may not feel the same. Around the eighteen months different reactions of babies can be defined front to the approach and the distanciamento of the mother, not being possible to define the reasons that take the different types of attachment. It is observed that in the presence of a strange person, ahead of the removal and the return of the mother, some children reveal a standard of safe attachment, looking it in its return and being easily comforted for it, exactly having protested to its exit. This standard of kept attachment being, in general, in such a way favors the adequacy of posterior relationships in infancy as in the adult life. On the other hand, some babies demonstrate a unsafe attachment that can be observed with different manifestations.
The children who do not complain the removal of the mother, preventing it its return and continuing to play as if nothing of uncommon it had happened, are identified with having a evitativo attachment to the reference figure. The resistant attachment, in turn, is revealed by the babies who, when the mother leaves, are aflitos and, when return, is come close and moved away alternatingly from it. The persistence of the evitativo attachment and the resistant attachment leads to consolidate the search of unsafe and unstable relationships, in which the individual hardly reaches a satisfactory standard of based affective exchanges in relations reliable mutual. Zavaschi, Brunstein and Costa (2001) present one room type of attachment where it can ahead be identified between children who seem confused and with fear of the removal and the approach of its mothers.
