What is already known on this subject Speech and language delay (SLD) is among the most common developmental disorders in early childhood and often co-occurs with feeding and swallowing difficulties. Both speech and swallowing rely on shared neuromuscular and motor planning processes, suggesting a potential link between the two. Previous studies indicate that early feeding/swallowing challenges may serve as risk indicators for later language impairments. However, existing research has primarily focused on communication and learning outcomes, with limited attention given to swallowing performance in children with isolated SLD and the psychosocial impact on their families. What this paper adds to the existing knowledge This study demonstrates that children with SLD exhibit significantly poorer swallowing performance and oral motor function compared to typically developing peers, despite showing no clinically significant nutritional limitations. It also highlights that families of children with SLD experience lower quality of life and greater daily challenges related to feeding and swallowing. By excluding confounding conditions such as neurological disorders and autism, this study provides clearer evidence of the association between SLD and swallowing dysfunction, as well as its negative impact on families-an area that has been largely underexplored in the literature. What are the potential or actual clinical implications of this study? The findings underscore the need for clinicians to assess swallowing and oral motor skills in children presenting with SLD, even when overt feeding problems are not reported. Early identification of swallowing difficulties can support timely interventions that may mitigate developmental challenges. Moreover, given the demonstrated impact on families, clinical management should incorporate caregiver support and family-centered approaches. Integrating swallowing assessments into routine SLD evaluations could improve diagnostic accuracy, guide multidisciplinary interventions, and ultimately enhance both child outcomes and family quality of life.
