Hey Susan
Hey Susan is a free mobile AI assistant for pregnancy and childhood, available on iPhone and Android. It functions as a conversational companion that new parents can text at any hour, particularly during nighttime feedings and concerns. The app tracks feeds, sleep, and diapers while learning the baby's patterns over time, and proactively sends check-in messages to caregivers. It also asks about the parent's own well-being, including postpartum mental health. Unlike traditional baby logbooks, Hey Susan builds a persistent picture of each child by remembering details between conversations and refreshing them with new logs. It lays out checkups, milestones, and vaccines from pregnancy through age 18, providing stage-relevant information. The assistant is designed to notice when something seems off—such as a missed feed or skipped nap—and to keep important next steps in view until handled. The tool is explicitly not a medical device and does not provide diagnoses; it points users to their pediatrician for anything medical. It was created by parents Warren and Joanna after their own experience with a newborn's feeding difficulties and jaundice, aiming to provide personalized, proactive support rather than generic parenting information.
