Bottle-Feeding Challenges in Preterm-Born Infants in the First 7 Months of Life.

Preterm infants frequently experience oral feeding challenges while in the neonatal intensive care unit, with research focusing on infant feeding during this hospital stay. There is little data on symptoms of problematic feeding in preterm-born infants in the months after discharge. The purpose of this study was to describe symptoms of problematic bottle-feeding in the first 7 months of life in infants born preterm, compared to full-term infants. Parents of infants less than 7 months old completed an online survey that included the Neonatal Eating Assessment Tool-Bottle-feeding and questions about the infant's medical and feeding history. General linear models were used to evaluate differences in NeoEAT-Bottle-feeding total score and subscale scores by preterm category, considering other significant factors. Very preterm infants had more symptoms of problematic bottle-feeding than other infants. Current age, presence of gastroesophageal reflux, and anomalies of the face/mouth were associated with problematic bottle-feeding.
