Non-nutritive sucking habits—such as pacifier use, thumb sucking, and prolonged bottle-feeding—are common in early childhood. Although typical in the first months of life, their prolonged persistence can adversely affect orofacial structures, occlusal development, and speech. Parents play a key role in establishing and discontinuing these habits; therefore, their awareness is essential for timely prevention and intervention.
The theoretical section presents the stomatognathic system and the typical development of oral-motor functions, including sucking, chewing, swallowing, feeding, breathing, and speech. Special attention is given to factors influencing orofacial development, such as mouth breathing, feeding practices, and excessive pacifier use. The types of sucking habits and their effects on muscle function, swallowing, occlusion formation, and speech abilities are described in detail. The role of parents in preventing and eliminating these habits, the importance of awareness and preventive measures, and a multidisciplinary approach involving speech-language pathology, orthodontics, and pediatrics are also addressed.
The empirical section is based on a quantitative cross-sectional study conducted with a sample of 209 mothers of children of various ages. The aim of the research was to determine the extent to which parents are aware of the impact of sucking habits on children’s speech development and how this awareness relates to the duration and frequency of such habits. We also examined whether the level of awareness is influenced by parents’ educational level, the number of children in the family, their own childhood experiences with sucking habits, and how the duration of breastfeeding is associated with the persistence of sucking habits later on.
Findings showed that most children maintained sucking habits beyond 18 months of age. Overall, parental awareness of the impact on speech development was not demonstrably low and was rather high. Lower parental awareness was significantly associated with longer habit duration; longer duration was also linked to a higher likelihood of later articulation difficulties and a greater prevalence of malocclusion. Longer breastfeeding emerged as a protective factor against prolonged non-nutritive sucking habits. No associations were found between parental awareness and daytime sucking time, education level, number of children, or parents’ past experience with sucking habits.
