In cases group, feeding was begun two minutes before injection and continued for 45 seconds. In the control group injection was made without breast feeding. Pain assessment was performed with Douler Aigue Nouveaune [DAN] scale. In the case group 35.4% of newborns got 4 points and no one got more than 7 points according to DAN scale.
