Pacifiers may seem like a quick solution to quieting a fussy baby, but the risks versus benefits analysis is not as straightforward as it might initially appear.
On the plus side, the American Academy of Pediatrics' (AAPs') Sudden Infant Death Syndrome (SIDS)-reduction guidelines do include the recommendation that babies be given pacifiers during naps and at bedtime (but not to force it if your baby refuses a pacifier). If you’re breastfeeding, the AAP suggests waiting until breastfeeding is well established or until your baby is about a month old. This advice is based on research suggesting that babies who suck on pacifiers don’t sleep as deeply and wake more often than those who don’t—both factors believed to reduce the risk of SIDS.
While pacifiers may have that going for them, they’re also linked to higher rates of ear infections, diarrhea, yeast infections and dental problems. Pacifiers can also interfere with successful breastfeeding, which, like pacifiers, also helps your baby sleep lightly and has been proven to reduce the risk of SIDS as well as the likelihood that your baby will acquire the listed conditions above.
