Children engage in the events of the World Kindness Day festival through interactive activities aimed at promoting empathy and compassion. Schools and community centers organize workshops, storytelling sessions, and art projects where kids can express kindness through creativity. They may participate in charity events, such as making care packages for the needy or writing encouraging notes to be shared. By involving children in these activities, the festival cultivates a sense of responsibility and raises awareness about the importance of kindness in their daily lives.
