Apparently over 200 kids die each year in US because parents forget about them and leave them on the backseat. This gadget called the Baby’s Alert Child Minder can save a lot of lives. The device works by installing ”active buckle” on the child’s seat belt and by attaching the monitor on the car key’s or somewhere else. When the two are separated it sends an alarming sound to the monitor to prevent the bad parent not to forget the child in the car. However if you end up forgeting the keys and the child, might as well just shoot your self in the head.
