Early childhood is a crucial stage in human development, as it lays the foundation for later learning. In this regard, the role of teachers and parents is to provide diverse opportunities and environments that foster children's holistic development—physically, socially, cognitively, volitionally, and emotionally. Along these lines, García (2019) points out that children learn more effectively when they participate in repeated experiences that respect their initiative, allow them to act autonomously, and enable them to practice acquired skills within their own daily context, in interaction with significant figures.

In this way, through early stimulation and intervention, the aim is to positively impact the child's growth, optimizing their abilities in each of the areas of development, using resources and strategies that promote adequate care for children under 6 years of age, under a humanistic vision, understood as an approach that recognizes the child as a unique, dignified person and protagonist of their own development process, respecting their maturational pace, promoting their autonomy and fostering their comprehensive development.

In this context, the Universal Design for Learning (UDL) framework aims to promote optimal child development, prevent difficulties, and provide timely intervention based on individual needs. This refresher course will review the theoretical and neurological foundations, the main neurodevelopmental disorders, and various strategies and teaching resources that can be used for child stimulation and intervention.

The refresher course will have a theoretical-practical approach and its development will generate spaces for reflection on daily practice in relation to the care and interaction with early childhood.
