Objective:To investigate the initation time of breastfeeding, exclusive breastfeeding rates, and complementary feeding practices during the first six months of life among mothers who gave birth in a baby-friendly hospital.Materials and Methods:A cross-sectional study was conducted with 350 mothers. Demographic characteristics, obstetric history and information about breastfeeding initiation were collected at the hospital. Information about factors affecting breastfeeding duration and feeding practices of the infants were obtained at the end of six months.Results:Some 97.4% of the mothers initiated breastfeeding, 60.1% within the first hour. Exclusive breastfeeding was maintained for six months in 38.9%. Low education levels of mother/father, random breastfeeding, rare breastfeeding at night, nipple problems, bottle/pacifier use, and lack of social support were found associated with early cessation. Planned pregnancy [odds ratio (OR=2.02)] and vaginal delivery (OR=0.3) were found as the most important factors in early initiation, whereas antepartum breastfeeding education (OR=7.17) was the most important factor for exclusive breastfeeding duration in the logistic analysis. More than half (61.1%) of the infants were partially/bottle fed for six months; the most common reason was the belief that breast milk was insufficient.Conclusion:Efforts to encourage mothers and society to breastfeed exclusively should be made as part of a primary public health strategy to prevent early cessation of breastfeeding.
