PACi

A pacifier, commonly known as a pacifier, and in some regions as a paci, is a nipple-shaped teat attached to a shield that is placed in a baby's mouth to satisfy the sucking reflex and provide comfort. Pacifiers are widely used to soothe infants, help them settle to sleep, and calm during medical procedures. They are generally suitable for newborns and older infants, with variation in age recommendations.

The device typically consists of a nipple portion made of silicone or latex and a shield that prevents swallowing. Pacifiers may be one-piece or two-piece designs; they come in a range of shapes (orthodontic, conical, or rounded) and sizes calibrated to the child’s age and mouth size. Silicone is durable and maintains shape well, while latex is softer but wears more quickly. Cleaning guidelines vary by manufacturer but usually include regular washing with soap and water and periodic sterilization.

Use and safety considerations include supervising use, avoiding tying pacifiers to cords or clothing, and ensuring they are the appropriate size to prevent choking. Do not dip pacifiers in sweet substances, as this can contribute to tooth decay and an infant’s preference for sugary flavors. Replace worn or discolored pacifiers promptly.

Health and dental considerations note that prolonged pacifier use, especially beyond the second or third year, can affect dental alignment and bite development. Pediatric guidelines often advise tapering use as a child approaches age two to four and consulting a pediatric dentist if there are concerns.

Historically, pacifiers have a long lineage, with modern designs widely manufactured since the late 19th and early 20th centuries. The term paci is a colloquial form used in several languages to refer to this device.
