Natural rubber, also called India rubber or caoutchouc, is an elastomer that was originally derived from latex, a milky colloid produced by some plants. The plants would be ‘tapped’, that is, an incision made into the bark of the tree and the sticky, milk colored latex sap collected and refined...

History

In England in the 17th–19th centuries, a coral meant a teething toy made of coral, ivory or bone, often mounted in silver as the handle of a rattle. A museum curator has suggested that these substances were used as "sympathetic magic" and that the animal bone could symbolize animal strength to help the child cope with pain.

Pacifiers were a development of hard teething rings, but they were also a substitute for the softer sugar tit
Sugar tit
Sugar tit is a folk name for a baby pacifier, or dummy, that was once commonly made and used in North America and Britain. It was made by placing a spoonful of sugar, or honey, in a small patch of clean cloth, then gathering the cloth around the sugar and twisting it to form a bulb...

, sugar-teats or sugar-rags which had been in use in 19th century America. A writer in 1873 described a "sugar-teat" made from "a small piece of old linen" with a "spoonful of rather sandy sugar in the centre of it", "gathered ... up into a little ball" with a thread tied tightly around it. Rags with foodstuffs tied inside were also given to babies in many parts of Northern Europe and elsewhere. In some places a lump of meat or fat was tied in cloth, and sometimes the rag was moistened with brandy. German-speaking areas might use Lutschbeutel: cloth wrapped round sweetened bread, or maybe poppy-seeds. A Madonna

Pacifiers were settling into their modern form around 1900 when the first teat, shield and handle design was patented in the US as a "baby comforter". Rubber had been used in flexible teethers sold as "elastic gum rings" for British babies in the mid-19th century, and also used for feeding-bottle teats. In 1902 Sears Roebuck advertised a "new style rubber teething ring, with one hard and one soft nipple", and in 1909 someone calling herself "Auntie Pacifier" wrote to the New York Times to warn of the "menace to health" (she meant dental health) of "the persistent, and, among poorer classes, the universal sucking of a rubber nipple sold as a 'pacifier'." In England too, dummies were seen as something the "poorer classes" would use, and associated with poor hygiene. In 1914 a London

 doctor complained about "the dummy teat": "If it falls on the floor it is rubbed momentarily on the mother's blouse or apron, lipped by the mother and replaced in the baby's mouth."

Early pacifiers were manufactured with a choice of black, maroon or white rubber, though the white rubber of the day contained a certain amount of lead. Binky (with a y) was first used as a brand name for pacifiers and other baby products in about 1935 and is currently owned by Playtex Products, Inc. as a trademark in the U.S. (and a number of other countries).

Drawbacks

Pacifiers have been shown to interfere with breastfeeding
Breastfeeding
Breastfeeding is the feeding of an infant or young child with breast milk directly from female human breasts rather than from a baby bottle or other container. Babies have a sucking reflex that enables them to suck and swallow milk. It is recommended that mothers breastfeed for six months or...

Children who suck pacifiers may be more prone to ear infections (otitis media
Otitis media
Otitis media is inflammation of the middle ear, or a middle ear infection.It occurs in the area between the tympanic membrane and the inner ear, including a duct known as the eustachian tube. It is one of the two categories of ear inflammation that can underlie what is commonly called an earache,...

).

Some older infants may have delayed speech development due to the pacifier's constant presence in their mouths preventing them from practising their speaking skills.

Prolonged use past the first few years can cause dental problems.

Benefits

Researchers have found that use of a pacifier is associated with a substantial reduction in the risk of SIDS

. Researchers in Brazil have shown that neither "orthodontic" nor standard pacifiers prevent dental problems if children continue sucking past the age of three years.

Medical policies

The American Academy of Pediatric Dentistry's "Policy on Thumb, Finger and Pacifier Habits" says: "For most children there is no reason to worry about a sucking habit until the permanent front teeth are ready to come in."

A study of sudden infant death syndrome (SIDS) published in Pediatrics, the journal of the American Academy of Pediatrics (AAP) states that "It seems appropriate to stop discouraging the use of pacifiers." The authors recommend the use of pacifiers at nap time and bedtime throughout the first year of life. For breastfeeding mothers, the authors suggest waiting until breastfeeding is well established, typically for several weeks, before introducing the pacifier.

The British Dental Health Foundation's FAQ page recommends: "If you can, avoid using a dummy and discourage thumb sucking. These can both eventually cause problems with how the teeth grow and develop. And this may need treatment with a brace when the child gets older."

Adult pacifiers

Adult-sized pacifiers, consisting of a standard baby pacifier guard but a larger, wider nipple, are used by some members of the Adult Baby community. The nipples are often referred to as NUK5s, after the NUK brand of baby pacifiers manufactured by the German company MAPA GmbH. They are sold under the name NUK Medicpro L or NUK Size 5.

Recent studies have also shown that pacifier use among adults may cut down or completely eliminate snoring.

Prevalence of attachments to pacifiers and their psychological functions

It wasn’t until the late 1970s that researchers were able to dispel the notion that pacifiers were psychologically unhealthy and aberrant. Richard H. Passman and Jane S. Halonen at the University of Wisconsin-Milwaukee traced the developmental course of attachments to pacifiers and provided norms. They found that 66% of their sample of three-month olds in the United States demonstrated at least some attachment, according to their mothers. At six months of age, this incidence was 40% and at nine months, 44%. Thereafter, the rate of attachment to pacifiers dropped precipitously until, at 24 months of age and later, it was quite rare.

These researchers also provided experimental support for what were then only anecdotal observations that pacifiers do indeed pacify babies. In an unfamiliar playroom, one-year-old infants accompanied by their pacifier evidenced more play and demonstrated less distress than did babies without them. The investigators concluded that pacifiers should be considered to be attachment objects, similar to other security objects like blankets.

Passman and Halonen contended that the widespread occurrence of attachments to pacifiers as well as their importance as security objects should reassure parents that they are a normal part of development for a majority of infants.
