Technology can provide children new opportunities to dive into the internet and play online games. Parents are showing concerns towards losing the ability to observe children's accession to technological devices. It is also growing concern that technological addiction has some negative impacts on young children. The purpose of this study was to analyze young children's technology addiction level and their observed challenging behaviors. For this purpose, Technology Addiction Scale and Challenging Behavior Inventory was used to collect data. Participants were six years old children and data was collected from their parents. Results showed that the majority of young children were in the attentiveness group (67%). Their major technology addiction was online gaming and parents reported higher challenging behaviors for this group of young children. Gaining social skills and appropriate behaviors are very important for young children for their later success in school and community. For this reason, technology addiction of young children should be under supervision.
