In a cross-sectional analysis of 629 mother-infants dyads, breast-feeding (ever vs. never) was associated with decreased relative odds of a lower versus upper respiratory tract infection (adjusted odds ratio: 0.64; 95% confidence interval: 0.42–0.99). There was not a significant association between breast-feeding and bronchiolitis severity score or length of hospital stay.
