A<unk>  is a rubber, plastic, or silicone nipple substitute given to an infant to suckle upon between feedings to quiet its distress by satisfying the need to suck when it does not need to eat.<unk> s normally have three parts, an elongated teat, a mouth shield, and a handle. The mouth shield is large enough to prevent the child from attempting to take the<unk>  into its mouth, and so forecloses the danger that the child will swallow then choke on it.<unk> s have many different informal names: binky (American English), dummy (Australian English and British English), soother (Canadian English and Hiberno-English), and Dodie (Hiberno-English).
