Background: The pervasive presence of screens in toddlers' environments leads to earlier, longer, and more varied exposure to digital devices. Although they provide toddlers with developmentally inappropriate visual and auditory stimulations, only one study has investigated the effect of these screens on their sensory development. The current research, therefore, explores the links between screen use habits and sensory profiles in 6- to 36-month-old toddlers.

Methods: Data were collected online using two questionnaires: a questionnaire designed to gather information regarding the use of screens within households and the Dunn's Infant/Toddler Sensory Profile 2 Questionnaire to assess the toddlers' sensory profile.

Results: Significant differences in sensory processing based on screen exposure were found: 6- to 18-month-old toddlers showed higher sensitivity and registration scores related to greater direct screen exposure, while 19- to 36-month-old toddlers principally showed higher seeking scores related to greater direct and background screen exposure.

Conclusion: These behavioral patterns suggest that excessive screen exposure may impact sensory processing, reducing opportunities for active, multisensory interactions essential for development, emphasizing the need for guidelines to manage screen use in early childhood to promote optimal sensory and cognitive development.

Impact: Early screen exposure and sensory processing of 6- to 36-month-old toddlers are linked Potential risks of excessive screen exposure time in toddlerhood could include behavioral problems and hyperactivity through sensory over-responsivity patterns Monitoring and managing screen use in early childhood is crucial for optimal development and to reduce the risk of behavioral disorders in a digital age.
