Results: There were 24 (47%) infants who used a pacifier during the first few days of life and seven (29%) of these were exclusively breastfed. Pacifier use was less common among mothers who exclusively breastfed (p = 0.04). Pacifier use was more commonamong mothers whose income was less than 25 000 US dollars (p = 0.02), who were single (p = 0.002) and who did not have a college education (p = 0.03). No associations between pacifier use and feeding performance were observed.Conclusion: While lower socioeconomic status was related to pacifier use, feeding performance in the first few days of life was no different between those infants who did and did not use pacifiers after a full-term birth.
