A pacifier is a silicon or rubber that mimics the breasts usually given to kids to suck. This comes in handy for those kids who do not seem to calm down even after feeding or cuddling. It is evident that pacifiers help the kids to have a nice nap either during the day or at night relieving you from much of the struggle that is encountered by mothers with crying babies. Evidence-based research shows that pacifiers prevent a baby from sudden infant death (SID).
