おしゃぶり

Also known as dummy, binky, soother, teether

A pacifier is a rubber, plastic, or silicone nipple substitute given to an infant and toddler to suckle on between feedings to quiet their distress by satisfying the need to suck when they do not need to eat. Pacifiers normally have three parts: an elongated teat, a handle, and a mouth shield that prevents the child from swallowing or choking on it.
