Our children's first digital footprints are made before they can walk-even before they are born-as parents use fertility apps to aid conception, post ultrasound images, and share their baby's hospital mug shot. Then, in rapid succession come terabytes of baby pictures stored in the cloud, digital baby monitors with built-in artificial intelligence, and real-time updates from daycare. When school starts, there are cafeteria cards that catalog food purchases, bus passes that track when kids are on and off the bus, electronic health records in the nurse's office, and a school surveillance system that has eyes everywhere. Unwittingly, parents, teachers, and other trusted adults are compiling digital dossiers for children that could be available to everyone-friends, employers, law enforcement-forever. In this incisive book, Leah Plunkett examines the implications of "sharenthood"-adults' excessive digital sharing of children's data. She outlines the mistakes adults make with kids' private information, the risks that result, and the legal system that enables "sharenting."
