In an infant population with a short breastfeeding duration and using longitudinal patterns of infection, skin rash and respiratory symptoms, on average, our study confirmed a protective effect of breastfeeding on diarrhea events in early infancy, infrequent bronchitis/bronchiolitis and, to a lesser extent,infrequent otitis events up to 2 years but not on cold/ nasopharyngitis, skin rash or respiratory symptoms.
