Few studies have investigated breastfeeding in twins specifically, and even fewer have focused on the duration of breastfeeding of twin infants. Furthermore, in our literature search, we did not find studies of breastfeeding of twins investigating the effect of antenatal education on breastfeeding twins. Our hypothesis is that mothers of twins receiving specific antenatal counseling on breastfeeding should have a higher rate of breastfeeding than mothers who do not receive antenatal breastfeeding counseling. Therefore, the purpose of this study was to investigate the effect of specific antenatal breastfeeding counseling on the breastfeeding rates in twin pregnancies.
