Toward a speech-motor account of the effect of Age of Pacifier Withdrawal

The effects of prolonged pacifier use on language development in infants and toddlers

Pacifiers are a common soothing tool used by parents to calm and comfort infants and toddlers. While pacifiers can provide temporary relief, there is growing concern about the potential long-term effects of prolonged pacifier use on language and cognitive development. Previous studies have suggested that prolonged use of pacifiers may have negative consequences on language outcomes in infants and toddlers, especially during the first few years of life known to be a critical period for language development. Previous studies have shown that children who use pacifiers extensively have smaller vocabulary sizes at 1 and 2 years of age which can have subsequent effects on socioemotional. In addition, significant association between greater frequency of daytime pacifier use and worsening of cognitive outcomes was shown. Furthermore, research has shown a strong dose-response association between intense pacifier use up to 4 years of age and lower IQ at 6 years. Recently, the importance of oral motor movements and sensorimotor production for speech perception in infants as young as 6 months has been highlighted, raising important questions on the effect of oral motor movement restrictions at an early age. Together, these findings raise concern about the potential long-term effects of prolonged pacifier use on language and cognitive development at a critical time in child development. However, it is still debatable within the scientific field the potential relationship between pacifier use and language development in early life most likely due to the complexity of studying child development. This mini review aims to provide valuable insights for parents, caregivers, and healthcare professionals in making informed decisions and understand regarding pacifier use for infants and toddlers.

Sustained pacifier use is associated with smaller vocabulary sizes at 1 and 2 years of age: A cross-sectional study

Pacifier use during childhood has been hypothesized to interfere with language processing, but, to date, there is limited evidence revealing detrimental effects of prolonged pacifier use on infant vocabulary learning. In the present study, parents of 12- and 24-month-old infants were recruited in Oslo (Norway). The sample included 1187 monolingual full-term born (without visual, auditory, or cognitive impairments) infants: 452 (230 girls; 222 boys) 12-month-olds and 735 (345 girls; 390 boys) 24-month-olds. Parents filled out an online Norwegian Communicative Development Inventory (CDI), which assesses the vocabulary in comprehension and production for 12-month-old infants and in production only for 24-month-old infants. CDI scores were transformed into age- and sex-adjusted percentiles using Norwegian norms. Additionally, parents retrospectively reported their child's daytime pacifier use, in hours, at 2-month intervals, from birth to the assessment date. Maternal education was used to control, in the analyses, for the socio-economic status. We found that greater pacifier use in an infant's lifespan was associated with lower vocabulary size. Pacifier use later in life was more negatively associated with vocabulary size than precocious use, and increased the odds of being a low language scorer. In sum, our study moves beyond the findings of momentary effects of experimentally induced "impairment" in articulators' movement on speech perception and suggests that, from 12 months of age, constraints on the infant's speech articulators (pacifier use) may be negatively associated with word comprehension and production. RESEARCH HIGHLIGHT: 1.We examined the relationship between pacifier use and vocabulary sizes in production at 24 months of age and comprehension and production at 12 months of age. 2.Lifespan Pacifier Use (LPU) was negatively correlated with vocabulary sizes in comprehension and production among 12-month-old infants and negatively correlated with production for 24-month-olds. 3.Later pacifier use was found to be more negatively correlated with vocabulary size in infants, as compared to more precocious use. 4.The amount of pacifier use in the 2 months prior to a child's second birthday was predictive of a higher prevalence of low vocabulary scores in 24-month-olds.

A new technology for pacifier weaning: a thematic analysis

Introduction

Babies and toddlers often become accustomed to using baby pacifiers. However, pacifiers may harm children's health and lead to various problems, such as less frequent breastfeeding, shorter breastfeeding duration, dental deformities, tooth decay, recurrent acute otitis media, sleep disorders, and the potential for accidents. This study aims to introduce new technology that may prevent babies from becoming used to a pacifier (patent titled "Prevents Getting Used to Pacifier Baby, Number SA10609, Saudi Authority for Intellectual Property"). This study used a descriptive qualitative design.

Methods

The participants included three pediatricians, three psychologists, three dentists, three family doctors, and three mothers of babies and toddlers, with a mean age of 42.6 years old (SD = 9.51). Semi-structured interviews were used, and thematic analysis was conducted to generate a thematic tree.

Results and Discussion

The thematic analysis resulted in three themes: (1) the disadvantages of pacifier use, (2) the introduction of new technology for the patent, and (3) the expectations for this technology. The results showed that a pacifier might negatively affect the health of babies and toddlers. However, the new technology may prevent children from becoming used to pacifiers and protect them from any possible physical or mental issues.
