The personal information form and BSES-SF were administered to women in the hospital before the intervention. Breastfeeding education and counseling were provided via social media (WhatsApp) to support women for breastfeeding and to ensure the continuity of breastfeeding in the postpartum period. Breastfeeding education was given to women in the first four weeks after discharge from the hospital. After the breastfeeding education was completed via social media, the counseling process started. Counseling was conducted via social media with a question-answer method between the first and 6th months of postpartum.

The women in the control group were pre-tested at the hospital before discharge. The BSES-SF was re-administered by phone at the 3rd and 6th postpartum months. The control group received the routine breastfeeding postpartum educational training given to all women by healthcare personnel as part of the hospital procedures. Except for routine breastfeeding training, no intervention was applied to the control group.

Breastfeeding education was applied for four weeks.
