The study aimed to identify the informational, practical and emotional support that multiparous mothers had received from nurses in the early postpartum period.This is a descriptive and cross-sectional study on 278 multiparous mothers who took part in the research prior to their discharge from a maternity hospital in Ankara, Turkey. The instrument used was a 38-item questionnaire. Experiencing breastfeeding problems was the only statistically significant predictor of in-hospital supplementation (P < 0.01, OR 0.028, 95% CI 0.005–0.159). There were no statistically significant association between some predictor variables with regard to breastfeeding support and breastfeeding outcomes including in-hospital formula supplementation and breastfeeding problems. No significant associations are indicative for the need of more effective implementation of informational, practical and emotional breastfeeding support for multiparous mothers in easing their adjustment to breastfeeding. Nurses can encourage multiparous mothers to maintain breastfeeding through individual teaching, giving mothers a sense of security, providing understanding care and telling about what to do with regard to breastfeeding problems. Antenatal education and support could be more likely to make a difference.
