Breastfeeding has been shown to reduce infections in children. Our aim is to assess if exclusive breast feeding protects against pneumonia. Candidates were in 2 groups: 100 children who had severe pneumonia and100 children who did not develop pneumonia in the first 2 years.12% were exclusively breastfed for the first 6 months in “pneumonia group” compared to 32% in the “control group”, (OR: 3.5). Exclusive breastfeeding for 6 months protects against severe pneumonia.
