The Keppel Kids Playgroup is a casual morning gathering where kids can engage in art activities, free play, and outdoor fun in a playground and sandpit. It's an ideal setting for kids to make new friends and learn while having fun. The event is open to all and takes place during school terms. No specific details are provided about what to bring or the cost, but it seems to be a free and welcoming environment. The suitable age group appears to be preschool or early school age children, given the mention of a playground and sandpit.
