This study aimed to determine the effect of the finger feeding method applied by fathers on the transition time to oral feeding and sucking success in premature babies.

Premature babies followed in the Neonatal Intensive Care Unit will be randomly divided into two groups: control group and finger-feeding group. Babies in the experimental group will be breastfed by their father three times a day. Before nasogastric feeding, the baby will be allowed to suck his finger by putting his finger in his mouth for five minutes three times a day. This procedure will be applied three times a day (morning, noon and evening) for a full 7 days. Babies in the control group will be given only routine ward care (breast milk or formula via tube without stimulation of the pacifier or mother's finger). Preterm Baby Monitoring Form and LATCH Breastfeeding Diagnostic Measurement Tool will be used to determine the transition time to oral feeding and breastfeeding success.
