Pineda R, et al. - Authors investigated the infant and social factors that were associated with the pacifier use during the first few days of life and determined if it led to alterations in feeding performance. The recruitment consisted of 51 full-term infants and their mothers at Barnes-Jewish Hospital in urban St. Louis, USA, in 2015. Findings demonstrated that lower socioeconomic status was connected with the pacifier use. Nevertheless, feeding performance in the first few days of life did not appear to be different between those infants who did and did not use pacifiers after a full-term birth.
