text: A pacifier is a rubber, plastic, or silicone nipple substitute given to an infant or toddler to suckle upon between feedings to quiet its distress by satisfying the need to suck when it does not need to eat. Pacifiers normally have three parts: an elongated teat, a handle, and a mouth shield which prevents the child from swallowing or choking on it.
  Pacifiers have many different informal names: binky or wookie (American English), dummy (Australian English and British English), dokey (informal Scots), soother (Canadian English), and dodie (Hiberno-English). Properly speaking, a teether is another device used for a different purpose.
