Amid the boom of wearables came the birth of devices for babies. Fretful, gadget-loving parents can now choose from a range of mini monitors that hide in tiny socks, strap to chubby little legs, snap onto diapers, or pin to onesies. The pastel gizmos promise peace of mind by effortlessly tracking an infants’ vital signs, movements, and sleep while parents take a breather.

Several companies dance around the idea that the monitors could even help prevent SIDS, sudden infant death syndrome. Of course, the reason for the footwork is because they have no basis to make such a claim; none of these consumer devices has been adequately tested and approved as medical devices by the Food and Drug Administration.
