Obviously, with distinct interests, which reproduce different proposals and conceptions of what it is to be child and of the necessities that this phase presents. We can search in history some concerns with infancy, as well as with what it involves the slight knowledge of ' ' city sustentvel' ' , ' ' sustentabilidade' ' , to understand such questions better. In elapsing of the times, and mainly, as it discloses to Muller & Redin (2007, p.15), after 2 world-wide war, had, on the part of the state representatives, a concern with the children, the orphans of war. What to make with these small that, alone ones in the world, abandonments in the streets, they could come to be a problem for the future, for the proper society?

In this construction, she transfers herself to see the child to it as a future project, one ' ' to come-the-ser' ' , as she affirms Miguel Arroyo (2000). It is impossible to deny, therefore, that many scholars of infancy, in this historical passage, have brought for the quarrel the importance of this phase and its validity in the gift.
