Children at this stage have their first experience of separation from their families and of meeting other children. We welcome them with respect for their individuality and pace of development, providing a space of creativity and conducive to discovery, experimentation, exchange and games.

Your child will develop their capacities and self-confidence. The educational team creates a climate and an environment that promotes pleasure, the joy of discovery, for children to express themselves freely without being judged. Individual and collective activities alternate harmoniously.
