Brief Summary

Few studies have investigated breastfeeding in twins, and none have addressed the effect of antenatal counseling on breastfeeding twins.The purpose of this study is to investigate the effect of antenatal breastfeeding counseling on the breastfeeding rates in twin pregnancies.

Detailed Description

In singleton pregnancies, three randomized studies have recently examined the influence of antenatal breastfeeding education on the breastfeeding rates (Su et al. 2007; Mattar et al. 2007; Wong et al. 2014). Two of these studies did not find differences in the total breastfeeding rates between the groups that received and did not receive antenatal breastfeeding education at the infants' age of 6 months old (Su et al. 2007; Wong et al. 2014). However, Su et al. found higher exclusive breastfeeding rates for 6-months-old infants in the group that received antenatal counseling. In contrast, Mattar et al. 2007 found significantly difference in breastfeeding rates with individual counseling compared to non-counseling or only breastfeeding educational material with no counseling.

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.

Arm && Interventions

Group	Intervention	Description
Prenatal Counseling Group	Prenatal Counseling Group	Patients in the PCG will receive specific counseling on breastfeeding consisting of three different counseling sessions during prenatal visits given by one two midwives involved in the study. The information will include: breastfeeding importance; how to prepare the nipples and breast for breastfeeding; the main complications and difficulties during the breastfeeding process and how to identify and overcome them; breastfeeding techniques and alternative positions for the simultaneous breastfeeding of twins, for example, "double cradle", "cradle-football" or "double-football", using illustrations and hands-on demonstration with doll models. During the counseling sessions patients will have the opportunity to discuss questions on breastfeeding.

Primary Outcome Measures

Name	Time	Method
Mother´s total and exclusive breastfeeding rates	5 years	Comparison of mothers' total and exclusive breastfeeding rates between the Prenatal Counseling Group (PCG) and Control Group (CG) in the three evaluated periods (30-40-days-old infants, 90-days-old infants and 180-days-old infants.

Secondary Outcome Measures

Name	Time	Method
Twin infant´s breastfeeding rates	5 years	Comparison of the rates of twin infant breastfeeding rates between the PCG and CG until 180 days of infants' age.For this analysis, the data of patients who were still breastfeeding at 180 days of infants' age will be censored at the time of the last obtained information.
