The maternal aleitamento provides an only protein combination, lipdios, carboidratos, minerals, alive vitamins, enzymes and cells, as well as benefits the known and unquestioned nutricionais, imunolgicos, psychological and economic, conferring protection against gastrointestinal and respiratory infections (BIRTH and ISSLER, 2003). According to Silva and Souza (2005), the World-wide Organization of Sade (OMS), the Deep one of United Nations for Infncia (UNICEF) and the Health department praise the exclusive maternal aleitamento until the six months of age and from the etria band and conditions of life must there initiate the balanced feeding in accordance with, however they must continue with maternal milk until the two years. Thus, the maternal aleitamento if becomes crucial tool for the survival, development and health of just born. In this segment, Venancio et al (2002), concluded that the administration of other liquids beyond maternal milk in first the four months of life of the child can negative intervene with the absorption of nutrients and its availability, diminishing the amount of maternal milk ingested and to take the lesser ponderal profit and increase of the risk of diarrias, respiratory infections and allergies.
Practical the exclusive one and drawn out of the maternal aleitamento can contribute for the decline of the levels of infantile mortality, in accordance with Braga, Machado and Bosi (2008). Thus, the maternal aleitamento is extended for just-been born premature and interned in neonatais units, contributing for the development and matureness of these. This practical is promoted by a variety of professionals in health, responsible for the neonatal unit of a hospital, between them, the nurse. One of the great challenges of nurse, and of the multiprofessional team, to reach the objectives of the projects and programs of incentive to the maternal aleitamento, inhabits in the difficulty to understand the real reasons for which many women leave to suckle its children (SHE HISSES, 2000). According to Almeida, Fernandes and Arajo (2004), the nurse will have to be next during and after the childbirth, since this is the professional who more narrowly becomes related with the woman during the gravdico-puerperal cycle, assisting the suck mothers in the first ones of just-been born, so that the maternal aleitamento is initiated precociously, of preference immediately after the childbirth.
