Abundant evidence recognises breastfeeding as being associated with significant short and long-term health benefits for both infant and mother. Until recently, the role of breastfeeding as an independent factor in reducing risk for sudden unexpected infant death remained unclear. In October 2010, SIDS and Kids Australia held a consensus forum with international researchers and key stakeholders to review current evidence relating to safe infant sleeping recommendations. Following this forum and the publication of key reviews, the SIDS and Kids National Scientific Advisory Group has supported the decision that a critical threshold had been reached within the evidence that is supportive of breastfeeding as a specific risk reduction measure for sudden unexpected death in infancy. A sixth recommendation, Breastfeed baby if you can, will be included in the 2012 SIDS and Kids Safe Sleeping national public health campaign.
