Careful examination of any setting in which young children will spend any amount of time, to remove from it or place out of reach (in a closed closet or on an upper shelf, for example) anything that might prove a danger to the child, such as marbles, nuts, buttons, or removable parts (which might be swallowed), anything with sharp points or edges, or items painted with leaded or otherwise toxic paint. It also includes removing anything that might be damaged by children, such as a beautiful bowl or fine book, and covering exposed electrical outlets. Parents of infants will need to peri¬ odically analyze what their child is capable of doing and what new dangers might emerge as the child develops. When they go visiting with the child, they should also keep a watchful eye out and (if the social situation allows it) temporarily childproof the room they and the child will be in.
