An interview guide, entitled "Maternal Perception of the Onset of Lactation", was also used to obtain milk secretion data. Results found a mean onset of lactation of 78.2±18.7 hours (range=42 to 121 hours). The prevalence of delayed lactation onset was 43.6%(n=58). Slighly over half of participants (56.9%, n=33) were primiparous. Parity, total second stage of labor duration, duration of second labor stage beyond one hour, and perinea wound pain were the most significant predictors of delayed lactation onset.
