Fiona Smyth’s rainbow of gender-spectrum characters pair perfectly with Cory Silverberg’s magical explanation of human conception, pregnancy, and childbirth. As the text does not specify how the egg and sperm come together, this book offers a unique opportunity for families formed through adoption, surrogacy, intrauterine insemination, in vitro fertilization, or plain, old penis-vagina intercourse to fill in the gaps to match each child’s unique life story.
