Infant Bottle-Feeding: A Prospective Study of Infant Physiology and Parental Report Metrics.
Morgan Hines, Alaina Martens, Emily Zimmerman
PMID 37498287WHAT IT FOUND
Parent reports of infant bottle-feeding concerns matched longer sucking bursts, more cycles per burst, and stronger sucking pressure, but not how efficiently babies drank from bottles.
Key findings
01Parent-reported problematic bottle-feeding behaviors were significantly associated with infant non-nutritive sucking cycles per burst, burst duration, and amplitude.
02Parent-reported problematic bottle-feeding behaviors were not significantly associated with Oral Feeding Skill scale scores.
03A non-significant trend linked higher parent-reported Compelling Symptoms scores to lower Oral Feeding Skill proficiency.

What it does not show
The study included 52 full-term infants who had no prior diagnosed feeding disorder, so it does not show how these measures behave in infants with known feeding problems. The sample was homogeneous: 96% of parents reported being married, 89% reported at least a college degree, and 68% reported a master's or higher degree, so results may not generalize. Parent responses on the NeoEAT-Bottle-Feeding questionnaire are subjective, and the study measured associations rather than proving that one measure causes or predicts the other. The home setting could not be controlled for stimuli, and some infants had not used the specific research pacifier before, which could affect non-nutritive sucking signals. Exclusions required prior bottle-feeding experience and complete measures, and infants without these were often exclusively breastfed, so the findings apply only to bottle-feeding infants with complete data.
The easy way to misread this
Do not treat non-nutritive sucking patterns as a clinical test that confirms or rules out feeding problems. The study found correlations in full-term infants without diagnosed feeding disorders, and the research pacifier was not a standard clinical device.
