Immune stimulation through exposure to commensal microbes may protect against allergy development. Oral microbes may be transferred from parents to infants via pacifiers. We investigated whether ...pacifier cleaning practices affected the risk of allergy development.
A birth-cohort of 184 infants was examined for clinical allergy and sensitization to airborne and food allergens at 18 and 36 months of age and, in addition, promptly on occurrence of symptoms. Pacifier use and pacifier cleaning practices were recorded during interviews with the parents when the children were 6 months old. The oral microbiota of the infants was characterized by analysis of saliva samples collected at 4 months of age.
Children whose parents "cleaned" their pacifier by sucking it (n = 65) were less likely to have asthma (odds ratio OR 0.12; 95% confidence interval CI 0.01-0.99), eczema (OR 0.37; 95% CI 0.15-0.91), and sensitization (OR 0.37; 95% CI 0.10-1.27) at 18 months of age than children whose parents did not use this cleaning technique (n = 58). Protection against eczema remained at age 36 months (hazard ratio 0.51; P = .04). Vaginal delivery and parental pacifier sucking yielded independent and additive protective effects against eczema development. The salivary microbiota differed between children whose parents cleaned their pacifier by sucking it and children whose parents did not use this practice.
Parental sucking of their infant's pacifier may reduce the risk of allergy development, possibly via immune stimulation by microbes transferred to the infant via the parent's saliva.
Background
To successfully initiate and maintain breastfeeding for a longer duration, the World Health Organization's Ten Steps to Successful Breastfeeding recommends total avoidance of artificial ...teats or pacifiers for breastfeeding infants. Concerns have been raised that offering the pacifier instead of the breast to calm the infant may lead to less frequent episodes of breastfeeding and as a consequence may reduce breast‐milk production and shorten duration of breastfeeding.
Objectives
To assess the effect of restricted versus unrestricted pacifier use in healthy full‐term newborns whose mothers have initiated breastfeeding and intend to exclusively breastfeed, on the duration of breastfeeding, other breastfeeding outcomes and infant health.
Search methods
We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2016) and reference lists of retrieved studies.
Selection criteria
Randomised and quasi‐randomised controlled trials comparing restricted versus unrestricted pacifier use in healthy full‐term newborns who have initiated breastfeeding.
Data collection and analysis
Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. The quality of the evidence was assessed using the GRADE approach.
Main results
We found three trials (involving 1915 babies) for inclusion in the review, but have included only two trials (involving 1302 healthy full‐term breastfeeding infants) in the analysis. Meta‐analysis of the two combined studies showed that pacifier use in healthy breastfeeding infants had no significant effect on the proportion of infants exclusively breastfed at three months (risk ratio (RR) 1.01; 95% confidence interval (CI) 0.96 to 1.07, two studies, 1228 infants), and at four months of age (RR 1.01; 95% CI 0.94 to 1.09, one study, 970 infants, moderate‐quality evidence), and also had no effect on the proportion of infants partially breastfed at three months (RR 1.00; 95% CI 0.98 to 1.02, two studies, 1228 infants), and at four months of age (RR 0.99; 95% CI 0.97 to 1.02, one study, 970 infants). None of the included trials reported data on the other primary outcomes, i.e. duration of partial or exclusive breastfeeding, or secondary outcomes: breastfeeding difficulties (mastitis, cracked nipples, breast engorgement); infant's health (dental malocclusion, otitis media, oral candidiasis; sudden infant death syndrome (SIDS)); maternal satisfaction and level of confidence in parenting. One study reported that avoidance of pacifiers had no effect on cry/fuss behavior at ages four, six, or nine weeks and also reported no effect on the risk of weaning before age three months, however the data were incomplete and so could not be included for analysis.
Authors' conclusions
Pacifier use in healthy term breastfeeding infants, started from birth or after lactation is established, did not significantly affect the prevalence or duration of exclusive and partial breastfeeding up to four months of age. Evidence to assess the short‐term breastfeeding difficulties faced by mothers and long‐term effect of pacifiers on infants' health is lacking.
We conducted a randomized trial to test the hypothesis that mother's voice played through a pacifier-activated music player (PAM) during nonnutritive sucking would improve the development of sucking ...ability and promote more effective oral feeding in preterm infants.
Preterm infants between 34 0/7 and 35 6/7 weeks' postmenstrual age, including those with brain injury, who were taking at least half their feedings enterally and less than half orally, were randomly assigned to receive 5 daily 15-minute sessions of either PAM with mother's recorded voice or no PAM, along with routine nonnutritive sucking and maternal care in both groups. Assignment was masked to the clinical team.
Ninety-four infants (46 and 48 in the PAM intervention and control groups, respectively) completed the study. The intervention group had significantly increased oral feeding rate (2.0 vs. 0.9 mL/min, P < .001), oral volume intake (91.1 vs. 48.1 mL/kg/d, P = .001), oral feeds/day (6.5 vs. 4.0, P < .001), and faster time-to-full oral feedings (31 vs. 38 d, P = .04) compared with controls. Weight gain and cortisol levels during the 5-day protocol were not different between groups. Average hospital stays were 20% shorter in the PAM group, but the difference was not significant (P = .07).
A PAM using mother's voice improves oral feeding skills in preterm infants without adverse effects on hormonal stress or growth.
To enhance breastfeeding practices, the World Health Organization discourages pacifiers and bottle-feeding. However, the effect of artificial nipples on breastfeeding duration is poorly defined. The ...effects of 2 types of artificial nipple exposure on breastfeeding duration were evaluated: 1) cupfeeding versus bottle-feeding for the provision of in-hospital supplements and 2) early (2-5 days) versus late (>4 weeks) pacifier introduction.
A total of 700 breastfed newborns (36-42 weeks, birth weight >or=2200 g) were randomly assigned to 1 of 4 intervention groups: bottle/early pacifier (n = 169), bottle/late pacifier (n = 167), cup/early pacifier (n = 185), or cup/late pacifier (n = 179). The cup/bottle intervention was invoked for infants who received supplemental feedings: cup (n = 251), bottle (n = 230). Data were collected at delivery and at 2, 5, 10, 16, 24, 38, and 52 weeks' postpartum. Intervention effects on breastfeeding duration were evaluated with logistic regression and survival analyses.
Supplemental feedings, regardless of method (cup or bottle), had a detrimental effect on breastfeeding duration. There were no differences in cup versus bottle groups for breastfeeding duration. Effects were modified by the number of supplements; exclusive and full breastfeeding duration were prolonged in cup-fed infants given >2 supplements. Among infants delivered by cesarean, cupfeeding significantly prolonged exclusive, full, and overall breastfeeding duration. Exclusive breastfeeding at 4 weeks was less likely among infants exposed to pacifiers (early pacifier group; odds ratio: 1.5; 95% confidence interval: 1.0-2.0). Early, as compared with late, pacifier use shortened overall duration (adjusted hazard ratio: 1.22; 95% confidence interval: 1.03-1.44) but did not affect exclusive or full duration.
There was no advantage to cupfeeding for providing supplements to the general population of healthy breastfed infants, but it may have benefitted mother-infant dyads who required multiple supplements or were delivered by cesarean. Pacifier use in the neonatal period was detrimental to exclusive and overall breastfeeding. These findings support recommendations to avoid exposing breastfed infants to artificial nipples in the neonatal period.
Use of honey pacifiers by infants presenting to a pediatric clinic at a county hospital in Houston, Texas, was observed by several of our staff members. Although we could not find any published ...studies linking the use of honey pacifiers to infant botulism, we also could not find any studies assessing the prevalence of honey pacifier use in general.
We conducted a cross-sectional, descriptive study using a novel survey that had 19 items. The survey was administered to the parents of children up to age 12 months presenting to a county hospital pediatric clinic for well-child care in Houston, Texas, from February 2010 to April 2011.
There were 397 respondents. Approximately 11% of the respondents reported using honey pacifiers with their infant children. Reasons for use included tradition, infant preference, and perceived health benefits (eg, helps with constipation or colic). Approximately 20% of the honey pacifier users and 23% of the entire group reported knowledge of honey potentially causing an illness in children <12 months of age. Nearly 40% of all respondents also reported using herbal or folk remedies.
Honey pacifier use was relatively common among this population, seen in ∼1 out of 10 respondents. A majority of the mothers surveyed (∼80%) were unaware of the potential dangers of giving honey to infants under age 12 months. Herbal medicine use was also common.
Teething is a physiological process experienced by all children. However, many unrelated illnesses are blamed on teething.
The aim of this study was to assess mothers' beliefs toward teething and to ...investigate the practices preferred by mothers to alleviate symptoms that might accompany the teething process.
A cross-sectional study was conducted in Basra. The study population includes mothers of young children aged (6-30) months who had at least one erupted primary tooth, and who had no history of medical or systemic disease that might affect teething. Two hundred mothers of different age groups and educational backgrounds responded to a questionnaire that included information on the child's age and birth order, mother's age, level of education, occupation, number of children, beliefs toward teething symptoms, and the practices preferred to relieve the attributed symptoms. Data has been presented in numbers and percentages, the Chi-square test was performed where appropriate, and a
value of < 0.05 was considered significant.
All (100%) participants attributed at least one symptom or sign to the teething process. The most common symptoms reported were fever (70%), diarrhea (68.5%), and sleep disturbance (63.5%). Sixty-eight percent of mothers believed teething remedies were effective; only 10 (5%) did not give any treatment. Over half (62%) gave medications, such as antipyretics, antibiotics, and antidiarrheal agents. Some used teething gels (29%), pacifiers (50%), gum massage (22%), and hard foods such as biscuits and carrots (43.5%). Mothers of various educational levels reported attributed symptoms, and the result was statistically significant (
< 0.05). Mothers of a firstborn child were found to have a higher tendency to attribute symptoms to teething than those who had previous experience with children (
< 0.05).
Teething myths and misconceptions are common among mothers. The study identified a significant number of doctors, dentists, and pharmacists still attribute many symptoms and signs to teething despite the lack of supporting evidence. Therefore, the findings of this study highlight the need for continuous medical education and nationwide prospective studies to eradicate these false beliefs.
To investigate the association between pacifier use and bottle-feeding and unfavorable behaviors during breastfeeding.
A cross-sectional study was conducted with 427 babies/mothers. ...Socio-demographic, perinatal data, and information about the use of artificial nipples (pacifier and/or bottle) were collected through a questionnaire. The breastfeeding aspects regarding position, affectivity, sucking behavior, baby responses, and breast anatomy were evaluated through observation during breastfeeding. The chi-squared test and the multiple linear regression analysis were used to investigate the association between the variables.
The aspects of breastfeeding that showed higher percentages of the category “poor” were sucking behavior (22.5%) and position (22.2%). The group of infants who used pacifiers and/or bottle showed higher percentages in the poor and fair categories when compared with the good category for all five breastfeeding aspects evaluated (p<0.001). The linear regression analysis revealed that the increase in the number of unfavorable behaviors regarding position, affectivity, sucking behavior, and baby responses were independently associated with both pacifier and bottle use (β positive, p<0.05), while breast anatomy was independently associated only with bottle use.
The findings suggest that the use of pacifiers and/or bottle-feeding may be associated with unfavorable behaviors during breastfeeding, especially the use of bottle-feeding.
Investigar a associação entre uso de chupeta e mamadeira e comportamentos desfavoráveis à amamentação durante as mamadas.
Um estudo transversal foi conduzido com 427 bebês/mães. Foram coletados dados sociodemográficos, perinatais e sobre o uso de bicos artificiais (chupeta e/ou mamadeira) através de questionário. Os aspectos de amamentação referentes à posição, afetividade, adequação da sucção, respostas do bebê e anatomia das mamas foram avaliados através da observação durante a mamada. O teste qui-quadrado e a análise de regressão linear múltipla foram usados para investigar associação entre as variáveis.
Os aspectos de amamentação que apresentaram percentuais mais elevados da categoria ruim foram a adequação da sucção (22,5%) e posição (22,2%). O grupo de bebês que usavam chupeta e/ou mamadeira apresentou percentuais mais elevados nas categorias ruim e regular quando comparados com a categoria bom para todos os cinco aspectos da amamentação avaliados (p <0,001). A análise de regressão linear revelou que o incremento do número de comportamentos desfavoráveis referentes à posição, afetividade, adequação da sucção e respostas do bebê estavam associados de forma independente tanto ao uso de chupeta quanto ao uso de mamadeira (β positivo, p <0,05), enquanto que anatomia das mamas estava associado de forma independente apenas com o uso de mamadeira.
Os achados sugerem que o uso de chupeta e/ou mamadeira pode estar associado a comportamentos desfavoráveis durante amamentação, em especial, o uso de mamadeira.

Pacifiers have been shown to affect maxillary growth related to the anatomic structure of the palate and forces placed upon it during sucking. This study compares and evaluates the mechanical ...behavior of pacifiers of different design and size (i.e., fit), identified by brand and size, positioned in age-specific palatal models with respect to both contact area and force when subjected to peristaltic tongue function and intraoral pressure related to non-nutritive sucking.
Nonlinear finite element analyses were used to simulate dynamic mechanical interaction between the pacifiers and palates. Time-varying, external pressure loads were applied which represent intraoral pressure arising from non-nutritive sucking and peristaltic behavior of the tongue. The silicone rubber pacifier bulb was represented using a hyperelastic material model.
Results from the finite element analyses include deformation, stress, strain, contact area, and contact force. Mechanical interaction was evaluated in terms of the spatial distribution of the contact area and force between the pacifier and the palate. The resulting palatal interaction profiles were quantitatively compared to assess how pacifier fit specifically affects the support provided to two areas of the palate, the palatal vault and the Tektal wall.
Pacifiers interact with the palate differently based on their fit (i.e., design and size) regardless of whether they are labeled conventional or orthodontic. Finite element analysis is an effective tool for evaluating how a pacifier's design affects functional mechanics and for providing guidance on biometric sizing.
Approximately 3500 infants die annually in the United States from sleep-related infant deaths, including sudden infant death syndrome (SIDS), ill-defined deaths, and accidental suffocation and ...strangulation in bed. After an initial decrease in the 1990s, the overall sleep-related infant death rate has not declined in more recent years. Many of the modifiable and nonmodifiable risk factors for SIDS and other sleep-related infant deaths are strikingly similar. The American Academy of Pediatrics recommends a safe sleep environment that can reduce the risk of all sleep-related infant deaths. Recommendations for a safe sleep environment include supine positioning, use of a firm sleep surface, room-sharing without bed-sharing, and avoidance of soft bedding and overheating. Additional recommendations for SIDS risk reduction include avoidance of exposure to smoke, alcohol, and illicit drugs; breastfeeding; routine immunization; and use of a pacifier. New evidence and rationale for recommendations are presented for skin-to-skin care for newborn infants, bedside and in-bed sleepers, sleeping on couches/armchairs and in sitting devices, and use of soft bedding after 4 months of age. In addition, expanded recommendations for infant sleep location are included. The recommendations and strength of evidence for each recommendation are published in the accompanying policy statement, "SIDS and Other Sleep-Related Infant Deaths: Updated 2016 Recommendations for a Safe Infant Sleeping Environment," which is included in this issue.
Pacifier Use and Exclusive Breastfeeding in Brazil Buccini, Gabriela dos Santos; Pérez-Escamilla, Rafael; Venancio, Sonia Isoyama

Background:
Exclusive breastfeeding (EBF) rates for infants younger than 6 months have increased in Brazil, although at the current pace of improvement it would take 6 years to reach an EBF rate of ...50%. Thus, it is important to identify relevant modifiable key risk factors for the premature interruption of EBF.
Objective:
This study aimed to find out if pacifier use is an independent risk factor for the interruption of EBF among Brazilian infants.
Methods:
We conducted secondary cross-sectional data analyses of 2 waves of infant feeding surveys conducted in 1999 and in 2008 in the Brazilian state capitals and Federal District (N = 42 395 children < 6 months). Multivariate logistic regression was used to test the association between pacifier use and the risk of interruption of EBF in a pooled sample and within each survey wave, adjusting for socioeconomic, demographic, and biomedical confounders.
Results:
In the pooled sample, a third of the infants were exclusively breastfed (32.7%) and almost 50% had used a pacifier. Whereas EBF prevalence among infants increased from 25.1% in 1999 to 40.3% in 2008, pacifier use prevalence decreased from 58.5% to 41.6% in the same time period. Pacifier use was strongly associated with the risk of interruption of EBF in 1999 (adjusted odds ratio AOR = 2.65; 95% confidence interval CI, 2.38-2.94), in 2008 (AOR = 3.18; 95% CI, 2.81-3.60), and in the pooled sample (AOR = 2.77; 95% CI, 2.63-2.91) after adjusting for key confounders.
Conclusion:
Pacifier use was the strongest risk factor for EBF interruption. Effective strategies to reduce pacifier use among infants younger than 6 months may further improve EBF rates in Brazil.
