FAQs

Everything you need to know before your first class.

Think of our classes as unique spaces where curiosity, confidence, and creativity are fostered through fun sensory play. Each themed class feels like a new immersive world where kids are introduced to new textures and activities in a gently structured environment, and parents are invited to join the fun. If you need a breather, want to watch from the sofa, or get some work done, you're welcome on the sidelines. Plus, leave the post-play cleanup to us!
