The German Study of Sudden Infant Death examined the relationship between the type of infant feeding and Sudden Infant Death Syndrome (SIDS). Over 1300 babies were studied.
The results of this study show a decrease in sudden infant death syndrome by ~50% at all ages throughout infancy. This is significantly higher than a previous study showing a reduction of SIDS by 36% in breastfeeding infants.
In their study, 73% of the infants that died of SIDS died before 6 months of age. The Back to Sleep campaign over the past 20 years has also reduced the risk of SIDS, therefore the authors recommend combining the advice that infants sleep on their backs with advice to breastfeed for at least 6 months.
