Sucking on a pacifier requires forward positioning of the tongue, thus decreasing this risk of oropharyngeal obstruction. The influence of pacifier use on sleep position may also contribute to its apparent protective effect against SIDS.

Do pacifiers decrease SIDS?

Pacifiers aren't just for soothing colicky babies anymore. A new study has found that use of a pacifier during sleep reduced the chances of a baby suffering from sudden infant death syndrome (SIDS) by 90 percent.

Does sleeping with a pacifier increase risk of SIDS?

For pacifier use during last sleep, the SORs calculated using univariate and multivariate ORs are 0.47 (95% CI: 0.40-0.55) and 0.39 (95% CI: 0.31-0.50), respectively. Conclusions: Published case-control studies demonstrate a significant reduced risk of SIDS with pacifier use, particularly when placed for sleep.
