Participants will include first-time breastfeeding women and the infants' fathers who have singleton births and full term healthy infants. Eligible parents who consent to participate will be randomized into either the intervention group or the control group. The control group will receive standard postpartum care, which is routine care in the hospital and community related to breastfeeding. The intervention group will receive standard postpartum care, plus a multifaceted support intervention that includes: (1) a professional-based in-hospital visit in the first two days postpartum that uses a take-home workbook, breastfeeding booklet, and video, (2) two follow-up emails in the first and third week postpartum, (3) one telephone call to the mother at two weeks, and (4) access to a secure study website for a three month period. All of the components in this intervention will contain extensive information on coparenting and breastfeeding. Follow-up data will be collected by the method chosen by participants, either by web-based survey or telephone interview. This data will be collected by a research assistant blinded to group allocation and data collection points will be at 6 and 12 week postpartum.
