According to the Window Covering Safety Council, infants and young children can accidentally strangle on window cords. Toddler and older children can strangle on dangling cords after climbing onto the bed to look out a window, and from their crib even infants can grab cords and put them around their necks. That's why the U.S. Window covering industry has continually redesigned window coverings for improved cord safety. Just make a simple call, or visit them on the web, and they will send you a free set of devices for child proofing your windows.
