Early childhood education (ECE) encompasses, at its most basic level, all forms of education, both formal and informal, provided to young children up to approximately 8 years of age. Some of the benefits include a diminished risk of social-emotional mental health problems and increased self-sufficiency as children mature and enter adulthood. It is during this period that children go through the most rapid phase of growth and development. Their brains develop faster than at any other point in their lives, so these years are critical. The foundations for their social skills, self-esteem, perception of the world and moral outlook are established during these years, as well as the development of cognitive skills. Lately, digital literacy and its practices are added as a need for future personal and professional development of children and developing digital competence already at kindergarten level can also help to raise awareness on safety issues and build critical thinking among them regarding content and devices that they use. This paper describes a new approach in supporting the development of digital literacy skills of preschoolers aged 5 to 6 in the context of Human-Computer Interaction (HCI) students volunteering for ICT activities in kindergarten along with building edutainment applications. There is also a report of key digital competences established by the kindergarten teachers involved, and monitored for formation during the activities.
