The provision of breast milk is essential for preterm infants as it provides unique health benefits that are unmatched by other types of feeding [1-3]. However, breastfeeding presents unique challenges for preterm infants that include establishing and maintaining the mothers' milk supply and transitioning the infant from gavage feeding to breastfeeding [4]. One of the issues that presents during the transition to breastfeeding is that mothers of preterm infants are rarely available for all oral feedings during hospitalization; this makes it necessary for infants to receive oral feedings by other method, usually bottle feeding.
