Assessing the flow rate of different bottles and teats for neonates with feeding difficulties: An Australian context

Abstract

To compare flow rates for Australian bottle/teat systems marketed as 'slow' or 'extra-slow' flow, and to examine flow consistency within each teat type. Established assessment methods were used to test 27 types of teats. Fifteen teats of each type were tested by measuring the amount of infant formula extracted in 1-min by a breast pump system. Teats were compared within 'slow' and 'extra-slow' categories, a coefficient of variation was calculated for each teat type, and a cluster analysis was performed to group teats with similar flow. There was significant variability observed between teats in the same 'slow' and 'extra-slow' categories, and sometimes between teat brands. Cluster analysis revealed 5 clusters. Many teats were considered to have moderate to high variability in flow rate. This study provides information regarding Australian bottle/teat systems. This is of relevance to those who support the neonatal bottle-feeding journey, particularly with premature or medically complex neonates.research.
