The concept of early metabolic (nutritional) programming, i.e., the idea that an environmental or nutritional stimulus or insult during critical periods of development may affect health later in life, has been widely accepted. In 2014, the Polish Society for Paediatric Gastroenterology, Hepatology and Nutrition published a position paper on the nutrition of healthy infants and in 2015, one on breastfeeding. This document is an update of both previous documents. Evidence for the recommendations was obtained by adapting trustworthy guidelines developed by scientific societies, renowned institutions, and expert organizations. A draft of the document was sent to all co-authors and future users for review and further comments. All critical feedback was considered, and changes were incorporated as necessary. Part of this document is a summary of infant feeding for everyday use by parents/guardians. An update of current recommendations is planned for no later than 5 years from now.
