Effects of parity and weaning practices on breastfeeding duration.

The purpose of this project was to examine (a) patterns of breastfeeding and (b) duration with parity and breastfeeding experience, and (c) mothers' reasons for termination of breastfeeding. A convenience sample of 120 breastfeeding mothers was followed by home visits and telephone for 20 weeks after delivery. The sample consisted of 69 primiparas, 40 multiparas with previous breastfeeding experience, and 11 multiparas with no prior breastfeeding experience. Parity was not significantly associated with the continuation of breastfeeding but there was a trend toward a difference made by breastfeeding experience. Inadequate milk supply and employment were the two most common reasons reported for weaning. Implications for support in the workplace and for first-time breastfeeding mothers are discussed.
