Authors' conclusions: breastfeeding protects against sudden infant death syndrome (SIDS). This effect is greater when breastfeeding is exclusive. The recommendation to breastfeed should be included in the messages to reduce the risk of SIDS.
Reviewers' commentary: despite some methodological limitations of the study evaluated, breastfeeding should be recommended in both maternity and pediatric primary care offices due to its many advantages, including its possible protective effect on sudden infant death syndrome. Among the tips for its prevention (back sleeping position, pacifier use when breastfeeding is well established), breastfeeding should be recommended as another protective factor.
