The Finnish researchers are unsure why the use of a pacifier might lead to an ear infection, but theorized it may have something to do with the change in pressure equilibrium inside the ear caused by the sucking.
Pacifier nipples do wear down with age and use, so check the binky thoroughly before placing it in your baby's mouth. Look for discoloration as well as holes, tears, and weak spots that could cause the nipple to break off when sucked, putting your baby at risk of choking. Some nipples also become sticky with age.
