In-hospital formula supplementation of breastfed infants negatively impacts breastfeeding duration. Infants from low-income families have some of the lowest exclusive breastfeeding rates in the United States. The objectives of this study were to identify (1) reasons low-income breastfeeding mothers begin in-hospital formula supplementation and (2) risk factors for in-hospital formula supplementation. We surveyed 150 low-income mothers in a Washington, DC, clinic. Sixty percent had initiated breastfeeding, and 78% of these breastfed infants received formula supplementation in the hospital. There was no clear medical need for supplementation for 87% of the breastfed infants receiving supplementation. Infants of mothers who did not attend a prenatal breastfeeding class were almost 5 times more likely to receive in-hospital formula supplementation than those infants whose mothers had attended a class (OR, 4.7; 95% CI, 1.05-21.14). Improved knowledge about breastfeeding among nursing and medical providers is important to minimize unnecessary formula supplementation for breastfed infants.

Clients of WIC initiated breastfeeding at a high rate but either supplemented with formula or stopped breastfeeding for reasons that could be remedied by improved prenatal education, encouragement of exclusive breastfeeding in the hospital, and more outpatient support.

All 3 teaching methods were time-efficient and produced important gains in knowledge and confidence, with residents in the IBCLC group demonstrating greatest improvement in knowledge and a higher rating of their teaching method. Our study provides support for 3 methods of teaching residents breastfeeding management and demonstrates that IBCLCs are well-received as interprofessional educators.
