Breast engorgement: patterns and selected outcomes.

For 14 days following birth, 114 breastfeeding mothers rated their level of breast engorgement twice daily, using a six-point engorgement scale. Individual engorgement ratings were plotted by intensity over time to provide a visual display of each subject's breast engorgement experience. Four distinct patterns of breast engorgement emerged; mothers experienced either a bell-shaped pattern, a multi-modal pattern, a pattern of intense engorgement, or a pattern of minimal engorgement. Characteristics of mothers and infants, and feeding frequency were similar across the four breast engorgement patterns.
