Conclusion
CF
The mixed method of CF showed greater adherence at seven, nine, and 12 months of age in children compared to the PLW and BLISS methods. In addition, among those children who did not adhere to the method they were randomized to, the majority followed the mixed method. Therefore, the mixed method appears to be a feasible approach to guide families in the introduction of CF. Family and maternal variables, such as family income, schooling, daily working hours, type of delivery, and infant variables, such as breastfeeding at hospital discharge and EBF until six months of age, were not associated with adherence to the mixed method. Further studies are needed to examine adherence to different methods of CF, with special attention to the strategies used to evaluate adherence. The authors also reinforce that CF is associated with cultural aspects of food, and the generalization of data should consider such aspects.The authors are grateful for the efforts of all researchers in the study and the willingness of all participants.
