Brindami aims to stimulate the development of social behaviours (e.g., sharing toys, making a request, managing emotions) in order to promote the well-being of children in the interaction with others. The program proposes a special modality, namely the use of a puppet (Brindami) which directly addresses the children. The program was implemented for the first time in 1997 and since, over 80 000 children have benefited from the visits of the joyous and energetic little mouse in their childcare centre. Two studies suggest that the program has beneficial effects. In the context of this project, the program will be enhanced (Brindami+).
