I first heard about Cory Silverberg’s work as a sex writer and educator through my work as an editor of the sex workers’ magazine $pread, back before either of us were parents. Years later, when I was pregnant with my second child, Cory ran a kickstarter campaign to publish his first children’s book, What Makes a Baby. Perfect timing! I started to read this illustrated guide to how babies are made “that works for every kind of family and every kind of kid” to my older daughter while her brother was in utero. (Incidentally, one of her first questions was, “Mommy, are your eggs wearing the same shoes as that egg?”) It remains one of her favorite books, though her questions have gotten more sophisticated over the years.
