the insertion of digital media devices has been increasingly prevalent in children's daily lives. The literature lacks evidence about the repercussion of media on children's development, therefore, further studies are needed to monitor the use and effect of these media.

to verify the viability of an intervention program based on active interactive media for children aged between 24 and 36 months.

Feasibility study in which 32 children enrolled in the nursery II of the educational institution, aged 24 to 36 months, and their parents/guardians, were invited to participate this study. Children were randomized into two groups: 1) GMIA: children used media actively (games) and GMIP: children used media passively (viewing content). Both groups participated in the intervention for 30 minutes, twice a week, for 4 weeks. Measures: Primary outcome: feasibility of the study regarding the criteria related to the intervention program with interactive media. Secondary outcome: adherence, acceptability, structure, and adequacy of the program to the school environment; degree of satisfaction and acceptability of messages and links and preliminary child development outcomes. Before and after 4 weeks of intervention, the children were assessed for child development, receptive vocabulary, and analysis of the Daily Record Chart on the use of interactive media at home.

Of the 32 eligible children, 22 children participated in the intervention, with an average of 17 children per meeting. As for acceptability, all parents (n= 32) signed the informed consent form, however, only 15 children (46.8%) were able to complete all stages of the program. As for the suitability of the proposal to the school environment, it was adapted after minor adjustments to the environment. Regarding the structure of the program, an “ideal” duration of 30 minutes of interventions was observed and that the children's interest was greater in the active media group. Most parents reported being quite satisfied with the program, 90% did not feel uncomfortable or dissatisfied with the messages and calls, and 31% correctly answered the daily media record chart over the four weeks. In the analysis of child development, it was observed that there was no statistically significant difference in the pre and post intervention results.

The need for adjustments in the procedures used in the program was identified, which led to structural changes, such as defining the duration of sessions; withdrawal from the daily record chart and changes in the places where the intervention was carried out. In view of the data obtained, it can be concluded that the feasibility study obtained satisfactory results and the changes made allow continuing with the intervention program with interactive media in the educational environment with a longer duration.

As it is a feasibility study, the results found in the present study affirmed the importance of it for carrying out a large-scale study, to continue with the intervention program with interactive media in the educational environment with a longer period. of duration.
