Babies Laugh Out Loud – Glasgow July 2024

Monday was the World Premiere my new show Babies Laugh Out Loud. It’s a show for babies and about babies. It is about my research into the science of baby laughter. After 12 years of doing this research, it was a delight to finally present it direct to babies themselves.

i was honoured to be able to present this to babies at the Glasgow Science Centre. Their IMAX stage was not the best location for a tiny show for tiny people. But the babies mostly didn’t mind. Thank you to Sam Wass and the organisers of International Conference on Infant Studies for making this possible. Huge thanks to my director Sarah Argent for co-creating this show. We enjoyed ourselves and audience were soooo cute.

We hope to bring the show to more places. So watch this space. If you have suggestions for suitable venues, please drop me a line at

The Laughing Baby

The science of happy babies

Written by Dr Caspar Addyman

The Laughing Baby is a popular science book about baby psychology. Long before babies can talk, they communicate their experience of the world through laughter and tears. Until now, however, psychologists and parenting experts have largely focused on moments of stress and confusion. Developmental psychologist Caspar Addyman decided to change that.

For nearly a decade Caspar has run the Baby Laughter project, collecting data, videos and stories from parents all over the world. He has learned that laughter and smiles – crucial to reinvigorate the weariest of parents – are of central importance at the start of life. They define our cognitive and emotional development and provide a fascinating window into what babies are learning.

Moving chronologically through the first two years of infancy, The Laughing Baby explores the origin story for our incredible abilities, and how understanding them is key to understanding ourselves.

The Laughing Baby is published by Unbound.
