Is it safe to use soothers or pacifiers?

No, It doesn't affect baby's throat in anyway. All that happens is that baby becomes dependent on the pacifier and would not like to get away with it. Yes, they might cause ear infections in the babies but if you keep them clean and limit the time of using it, this risk also goes away. Infant they lower the risk of SIDS. http://www.webmd.com/parenting/baby/features/using-pacifiers#1 http://www.mayoclinic.org/healthy-lifestyle/infant-and-toddler-health/in-depth/pacifiers/art-20048140
