RESUMO
PURPOSE: The lack of age-appropriate expectations for feeding acceptance patterns in early childhood is a barrier to early and accurate identification of pediatric feeding disorder (PFD). The objective of the study was to describe the process by which typically developing children 8-12 months of age accept or refuse bite presentations and their corresponding feeding behaviors, aiming to establish age-appropriate normative data for feeding acceptance. METHOD: Using cross-sectional methodology, we studied the proportion of bite presentations accepted, the type of feeding behaviors-passive, disruptive, expulsion, feeding concerns- observed at presentation and acceptance or refusal, and the duration between presentation to acceptance or refusal in 63 healthy infants between 8 and 12 months of age. Descriptive statistics and a one-way ANOVA were conducted to compare the effect of age and texture. RESULTS: Findings reveal high levels of bite acceptance of 80 % or > for children across ages, but with lower texture-specific differences. Both passive and disruptive behaviors were present even during acceptance of bites without any expulsion. Feeding concerns showed developmental trends with rapid reduction by 12 months suggesting improvement in oral feeding skills. The duration of acceptance and refusals revealed clear patterns by age and texture with an average of 3 s for acceptance but <1 s for refusal. CONCLUSIONS: This study describes bite acceptance patterns in a cohort of typically developing infants between 8 and 12 months of age by examining the acceptance of bites, frequency and type of feeding behaviors, and duration differences when children accept versus refuse a bite. Findings may be applied in the future to provide more sensitive detection of problematic feeding patterns to aid in the detection of pediatric feeding disorder.
