Feeding women during pregnancy and the child’s diet in the first two years of life (the first 1000 days) are crucial for development
and health at that time and in later stages in this line, the World Health Organization (WHO) points out in its Comprehensive
Implementation Plan on Maternal, Infant and Young Child Nutrition, which prioritizes actions to improve the development and
health of children in the world by 2025. The objective of this work is to analyze the contributions of breastfeeding from the approach
of Ramona Mercer, during the first 1000 days.
Methodology: Documentary research was carried out through a literature review. Optimal nutrition during the first 1000
days, ranging from conception to two years, is key to health throughout life. The review of several indexed articles shows that the
first 1000 days are of vital importance for the achievement of the best development and long-term health, and thus constitute a
fundamental strategic period for Primary Care and Collective Health, where the nursing professional provides care at the knowledge
of his or her specialized knowledge.
