Interaction of factors related to lactation duration.

Perceived social support and interpersonal dependency were studied as potential factors associated with lactation duration based upon previous breastfeeding experience. Inexperienced breastfeeding mothers perceived more social support than experienced breastfeeding mothers did. Perceived social support was not significantly correlated with lactation duration. An ancillary finding was that women providing a combination of breast milk and human milk substitutes had significantly lower social self-confidence than did mothers providing breast milk exclusively.
