Cory Silverberg is a sex educator and author who noticed that books about reproduction for kids didn't cover all families and birth situations.
Silverberg was inspired by a close friend who is not biologically related to his children.
That's when the author teamed up with illustrator Fiona Smyth to create What Makes A Baby. The book quickly spread among other families who didn't have a book that fit their story.
The son of a librarian and a sex educator, Silverberg breaks down the reproductive process on a granular level that applies to all people.
The initial self-published run of 4000 books sold out, and Seven Stories Press quickly signed Silverberg to a three book deal, including a larger pressing of What Makes A Baby via Random House.
In addition to the many ways babies are conceived, Silverberg and Smyth also strive to cover the various ways that babies are delivered.
The New York-based author describes the experience of putting this book together as "a dream come true - I now get to write queer sex education for everyone!"
