Baby Shows

Babies Laugh Out Loud

Babies Laugh Out Loud is the stage show version of Caspar’s Babies Laugh picture book series — bringing the science of baby laughter off the page and into the room.

A relaxed, interactive 30-minute performance for babies (0–18 months) and their grown-ups. Live puppetry, peekaboo, infant-friendly music, and joyful science — leading to a communal finale with The Happy Song, Imogen Heap and scientifically designed to make babies smile.

Caregivers are invited in, not just tolerated. Babies set the pace. Joy is the point.
