In the first five years of development there is a sequence of achievements that, in speed and relevance, is never repeated. In the first five years of life, the architecture of brain connections that will be the basis for lifelong learning achievements is built. Early language and math skills are also developed, which will account for a significant part of later academic achievement. As if this were not enough, the first five years of life also establish the socioemotional skills that allow us to relate to others in a healthy way and to deal with adversity and frustration.
