ABSTRACT BACKGROUND፡ This study was conducted to determine the breastfeeding practices among parous antenatal attendees in two teaching hospitals in Southwest Nigeria.METHODS: A cross-sectional study was carried out on 340 parous antenatal clinic attendees in two teaching hospitals in Ogun State, Nigeria. A structured questionnaire was used to obtain data on breastfeeding practices. Data were analyzed using Statistical Package for Social Sciences (SPSS) windows version 21.0 (IBM Corp., Armonk, NY, USA).RESULTS: Out of a total of 340 women, 319 (93.8%) breastfed their last babies. The median duration of breastfeeding was 15 months.  One hundred and thirty two women (38.8%) initiated breastfeeding within 30 minutes of delivery, and 200 women (58.8%) exclusively breastfed their babies for six months. The majority of the women, 299(87.9%k) did not report any problem associated with breastfeeding. Logistic regression analysis showed that women who had no breastfeeding problems were more likely to exclusively breastfeed their infants for six months compared to those with breastfeeding problems (AOR 3.4; CI 1.6-7.1; P=0.001). Similarly, women who got breastfeeding information from mass media were more likely to practice exclusive breastfeeding for six months compared to those that got breastfeeding information from other sources (AOR42.2; CI 3.1-568.5; P=0.005).CONCLUSION: Exclusive breastfeeding is suboptimal in Ogun State, Nigeria. Provision of breastfeeding information via mass media will assist in improving breastfeeding practice. Educating mothers on the techniques that help to prevent breastfeeding complications will also be beneficial.KEYWORDS: Breast milk, Breastfeeding, exclusive breastfeeding, Nigeria, Practices
