Objective:
To examine the relationship between maternal perceptions of insufficient milk and breastfeeding confidence using the Breastfeeding Self-Efficacy Scale.
Design:
Cross-sectional study.
Participants:
Two hundred and sixty-two in-hospital breastfeeding mothers in Japan.
Main Outcome Measure:
Breastfeeding self-efficacy was measured in-hospital and perception of insufficient milk was measured at 4 weeks postpartum.
Results:
Although most mothers intended to exclusively breastfeed, less than 40% were doing so at 4 weeks postpartum. Among the mothers using formula, 73% cited perceived insufficient milk as the primary reason for supplementation or completely discontinuing breastfeeding. Mothers' perception of insufficient milk at 4 weeks postpartum were significantly related to breastfeeding self-efficacy in hospital in the immediate postpartum period (r=.45, p<.001). Hierarchical multiple regression revealed that breastfeeding self-efficacy explained 21% of the variance in maternal perceptions of insufficient milk, and the contribution was independent of sociodemographic variables.
Conclusions:
Enhancing breastfeeding self-efficacy in the immediate postpartum period may reduce maternal perceptions of insufficient milk and the premature discontinuation or supplementation of breastfeeding. Additional research is warranted.

Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...
