Brief summary

Pacifier use reduces the risk of sudden infant death syndrome, and nonnutritive sucking has been shown to improve physiological balance and feeding in premature infants. Therefore, the risks and benefits of pacifier use should be carefully considered. In a study, it was reported that giving a pacifier on the 15th day did not change the prevalence and duration of breastfeeding, that using a pacifier was associated with a lower incidence of sudden infant death syndrome, and that giving a pacifier was a useful approach. Using a pacifier can help the baby calm down and adapt to the environment. When the literature was reviewed, conflicting results were reported regarding using a pacifier. However, the effect of using a pacifier on the baby's motor development and especially sensory processing skills has not been clearly investigated.

Detailed description

Pacifier use is a very common practice. It is often used in the early years of a child's life to help them fall asleep or to soothe and calm them down from teething pain. The age at which a pacifier is discontinued is usually around the age of three when the child goes to nursery. Observational studies have linked early pacifier use with breastfeeding problems leading to early weaning. However, randomized controlled trials have not shown a similar negative association between early pacifier use and successful breastfeeding, suggesting that pacifier use may be a sign of breastfeeding problems and not the cause. Pacifier use is often a topic of debate when parents and professionals aim to maintain and support breastfeeding. However, the literature supports the beneficial effects of pacifier use in infants because of the associated physiological benefits, such as digestion, behavioral organization, pain management, motor function, and sucking development. Pacifier use reduces the risk of sudden infant death syndrome, and nonnutritive sucking has been shown to improve physiological balance and feeding in premature infants. Therefore, the risks and benefits of pacifier use should be carefully considered. In a study, it was reported that giving a pacifier on the 15th day did not change the prevalence and duration of breastfeeding, that using a pacifier was associated with a lower incidence of sudden infant death syndrome, and that giving a pacifier was a useful approach. Using a pacifier can help the baby calm down and adapt to the environment. When the literature was reviewed, conflicting results were reported regarding using a pacifier. However, the effect of using a pacifier on the baby's motor development and especially sensory processing skills has not been clearly investigated. The aim of this study was to evaluate babies using a pacifier in terms of both motor development and sensory processing skills and to compare them with their peers who did not use a pacifier.

Interventions

It was planned to use the Test of sensory function in infants to evaluate the sensory development of infants. The test of sensory function in infants is frequently used to evaluate the sensory processing functions of infants aged 4-18 months. It is used to determine whether an infant has a sensory processing problem and to what extent. It consists of 24 items. The test of sensory function in infants requires the infant to be stimulated and interacted with various materials. The total score varies between 0-49 and the test has normative values for different age groups. Although it is used from the fourth month onwards, the most reliable and valid results are obtained between 7-18 months.

BEHAVIORALThe Peabody Developmental Motor Scales-Second Edition

The Peabody Developmental Motor Scales-Second Edition is a standardized, norm-referenced assessment instrument designed to evaluate both gross and fine motor skills in children aged 0 to 71 months. It is frequently employed in clinical, educational, and research contexts to detect motor developmental delays, monitor developmental trajectories, and inform intervention strategies. Notably, higher scores on the scale reflect superior motor performance, indicating better developmental outcomes

BEHAVIORALInfant/toddler sensory profile

The infant/toddler sensory profile is a questionnaire filled out by the child's primary caregiver to collect information about sensory processing abilities. The test evaluates sensory processing in 6 different areas. These items consist of general, visual, auditory, vestibular, tactile and oral sensory processing. The caregiver evaluates the child's behavior on a 5-point scale. One point means almost always and five points means almost never. The caregiver's responses are summarized using standard scoring procedures and then interpreted in terms of the impact of a child's sensory processing abilities on the child and their family's lives. The scores are normative for age and are important in assessing sensory development.

Peabody Developmental Motor Scales | Second Edition9-12 monthsThe Peabody Developmental Motor Scales-Second Edition is a standardized, norm-referenced assessment instrument designed to evaluate both gross and fine motor skills in children aged 0 to 71 months. The Peabody Developmental Motor Scales-Second Edition comprises six subtests, namely Reflexes, Stationary, Locomotion, Object Manipulation, Grasping, and Visual-Motor Integration, which collectively measure a broad spectrum of motor functions including postural control, locomotor abilities, object manipulation, and hand-eye coordination. The subtests generate three composite scores: the Gross Motor Quotient, Fine Motor Quotient, and Total Motor Quotient, offering a comprehensive evaluation of a child's motor competence. Notably, higher scores on the scale reflect superior motor performance, indicating better developmental outcomes

It is a questionnaire that questions the behavior and performance of a child between the ages of 0-3 (0-7 months and 7-36 months) regarding sensory processing. The test evaluates sensory processing in 6 different areas. These items consist of general, visual, auditory, vestibular, tactile and oral sensory processing. The caregiver evaluates the child's behavior on a 5-point scale. One point means almost always and five points means almost never.
