Intervention
The first and second parts of the breastfeeding education sessions were provided by the researcher when pregnant participants were between 31–34 and 35–37 weeks of pregnancy, respectively. The contents of breastfeeding education were designed according to a guidebook for monitoring “baby-friendly” hospitals in Iran [After giving birth, participants’ breastfeeding practice commenced according to the taught breastfeeding positions. Breastfeeding support was offered as required and participants could contact the researcher for additional support if they experienced breastfeeding issues. The two groups were located in separate rooms. On the 3rd, 5th and 7th day of the postnatal period, participants were contacted by telephone to confirm the assigned breastfeeding position being used.
