A method and apparatus to prevent children or physically/mentally challenged adults from closing the door, while at the same time allowing the normal function of opening and closing the door by an authorized person. The device is installed on the upper portion of the door frame, out of reach of children, by means of a fastener like “Velcro” adhered to the back of the apparatus. In the normal mode it prevents the door form closing. To allow the door to close, a string is pulled while closing the door.
