Buldur et al. (2020) found that finger feeding was an effective means of transitioning preterm infants from enteral (tube) to full breastfeeding. Researchers divided medically stable infants at 30-35 weeks of age into a syringe feeding cohort and a finger feeding cohort. The infants were fed using the syringe or finger feeding for 20 minutes, four times a day, for 10 days. While both groups at discharge were fully breastfed, the finger feeding group attained it faster, gained more weight, and had a shortened length of stay in the hospital. Additionally, they showed less signs of discomfort after feeding.
