Consensus report on guidelines for feeding infants and children from birth to 24 months. The consensus report from the National Academies of Sciences, Engineering, and Medicine is based on a review of 43 guidelines from authoritative governmental and nongovernmental organizations. It covers such topics as what to feed infants and young children and includes recommendations on breastfeeding, use of formulas, vitamins and supplements, food allergies, and substances to avoid or limit. It also discusses how to feed, with topics such as bottle use and propping, introduction of foods, and responsive feeding. The report concludes that although most guidelines are consistent, greater collaboration among the many groups issuing advice would improve future guidelines and enable coordinated dissemination, thereby improving the reach and uptake of recommendations.
