To assess mothers' knowledge of good infant nutritional practices, a survey was conducted by the Institute of Pediatric Nutrition. The survey addressed issues related to breast-feeding, the use of iron-fortified formula, frequent spitting up, the introduction of cow's milk into the infant diet, and the nutritional value of fruit juice. Mothers who responded to the survey had difficulty identifying the most appropriate choices. This article presents the survey results and discusses the implications for health care providers who care for children and their families.
