Abstract
Background: The critical time to continue or stop breastfeeding is during the first month after hospital discharge. Mothers receive lactation and physical support by fathers and others bottle-feeding human or formula milk to their infants.
Purpose: To describe the effect of feeders (mothers, fathers, and others) and different milk feeding on infants' weekly exclusive breastfeeding rates, from birth to 1 month after discharge.
Methods: This study was a secondary analysis of a descriptive longitudinal study of mothers' (full-term: n = 77; late preterm: n = 39) breastfeeding experience, frequency of feeding, and infant feeding behaviors. Mothers completed a weekly questionnaire of who (mothers, fathers, and others) fed their infants human or formula milk by direct breastfeeding or bottle-feeding.
Results: More than 60% of mothers reported fathers and others bottle-fed their infants. Exclusive breastfeeding rates were significantly higher when only mothers fed their infants at week 1 (P < .001), week 3 (P < .05), and week 4 (P < .05). Exclusive breastfeeding rates were negatively affected across time by bottle-feeding any human or formula milk for all feeders. When fathers bottle-fed their infants at week 1, the relative rates of exclusive breastfeeding at week 4 decreased to 52% (OR = 0.103; 95% CI, 0.26-0.404; P < .0001).
Implication for Practice: Individuals providing early bottle-feeding adversely affect breastfeeding outcomes. Providers need to address maternal and paternal knowledge gaps about early breastfeeding practice.
Implications for Research: Further research is needed to explore clinical standard of care for management of infant weight loss, early supplementation, and support of exclusive breastfeeding outcomes.
