Books
I’ve written books about babies, books for babies, and one book with nothing to do with babies whatsoever. Mostly they’re about laughter.
The Laughing Baby
Everything you ever wanted to know about why babies laugh so much — and why it matters. Draws on a decade of research, a lot of babies, and the occasional digression into evolutionary biology, neuroscience, and stand-up comedy.
“If you would like to really understand your baby – this is a must read!”
The Laughing Baby — Unbound, 2020
Babies Laugh™ Picture Books
Four board books for actual babies, illustrated by Ania Simone. Peekaboo, tickles, everything — the greatest hits of baby comedy, in book form.
Babies Laugh at Tickles · Babies Laugh at Peekaboo · Babies Laugh at Everything · Babies Laugh All Day Long
“My daughter LOVED this book and has been reading to her dolls!”

Help Yourself
A novel. No babies. (Well, almost no babies.) A comic thriller about self-help culture, con artists, and the remarkable human capacity for believing whatever we want to believe.
“An innovative and brilliant book which is full of surprises with every new chapter.”
The Happy Song
Not a book, but it starts here. In 2016, Caspar worked with Grammy-winning musician Imogen Heap to create a song scientifically designed to make babies smile. The Happy Song has been heard by more than 150 million people. It still works.
