Food parenting practices are feeding behaviours specific to parents which influence the health and wellbeing of their children. It is well established that parents play a significant role in the formation of a child’s eating behaviours and different food parenting practices can have negative or positive outcomes. Negative outcomes include eating behaviours such as disordered eating (e.g., dieting) which have the potential to manifest into clinical eating disorders (e.g., anorexia nervosa, binge eating disorder). Therefore, understanding which practices have a positive or negative influence on children’s eating behaviours is central to inform preventive interventions. Infants’ transition to solid foods is a critical period for parents to use positive food parenting practices; currently, early feeding education is dominated by information about what and when parents should feed infants. A considerable gap exists in the how of feeding, including practical strategies for parents. Establishing parents’ use of positive food parenting practices early in their children’s lives is likely an important step in preventing disordered eating, but one that has not yet been subject to critical research and development. Knowledge translation, a recognised method for turning research findings into practical applications, is increasingly being used in healthcare settings. This approach, guided by the Knowledge to Action Framework, was used to integrate this mixed methods program of research. The overall aim was to develop, implement, and evaluate a parents’ education package. A pragmatic approach was applied to this three-phased program, which incorporated five studies, each of which informed the next.
