Abstract 

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